In 1854 Mary Moffat paid another visit to the Colony, and was in consequence away from home when Robert returned from his journey to Moselekatse. Tidings reached him about that time of the death of his mother, the one who first instilled into his breast an enthusiasm for the missionary calling. She died as she had lived, a godly, consistent woman, and was called to the heavenly city at the age of eighty-four.

In 1856 Dr. Livingstone, after his unparalleled walk from Loanda, on the west coast, to Quillimane, on the east—from the shores of the Atlantic to those of the Indian Ocean—visited England. His visit, and the description he gave of the country and natives, rekindled missionary enthusiasm, a special interest being taken in the Matabele and Makololo tribes. The London Missionary Society resolved to establish missions among them. As the locality where the Makololo dwelt was in the midst of a marshy network of rivers, it was considered as a necessary condition of commencing the proposed missionary work that they should remove to a spot on the north bank of the Zambesi, opposite to where the Matabele dwelt on the south bank. The two tribes were, however, hostile to each other; and, to overcome this hostility, it was determined to simultaneously establish missions among both tribes. With this object in mind the Directors wrote to Robert Moffat, proposing that he should go for a twelvemonth to the Matabele, taking two younger men with him, and plant a mission among this people.

This letter reached him just as he had completed the translation and printing of the Old Testament; and, notwithstanding that he was then sixty-two years of age, and had already been forty-one years hard at work for the Society, he determined to go. He felt, however, that it was necessary for him to start at once, and prepare the minds of Moselekatse and his people for the coming among them of missionaries. Thus it came about that once again Robert Moffat quitted Kuruman, and started forward for the long and trying journey, through the African desert, to visit his old friend, and obtain his consent to the settlement of missionaries among his people.

Visiting the chief Sechele on the way, he pursued his course until he at length reached the headquarters of Moselekatse. The king was not very enthusiastic about receiving missionaries for himself and his people. He was somewhat suspicious; and his former experience with the American missionaries at Mosega had been rather unfortunate, the Boers having attacked the Matabele, and, after pillaging the mission station, carried the missionaries away with them. However, he would receive the new-comers,—but his friend Moshete must come also. "I love you," said he, "you are my father. These new men I do not know them. All men are not alike."

This African monarch had sufficient knowledge to know that, if the doctrines of the Bible prevailed among his tribe, his claims to divine honour would for ever cease. His warriors used to pay him homage as follows: "O Pezoolu, the king of kings, king of the heavens, who would not fear before the son of Machobane (his father's name), mighty in battle?" and with other similar marks of adulation. He also had a shrewd suspicion that the opening of the country for white men to come and settle, would mean, eventually, the downfall of the power of himself and his people? but in his friend Ramary, or Moshete, he had implicit confidence.

As an instance of the power which Moffat had obtained over this despotic chief of a fierce African tribe, it may be related that he prevailed upon Moselekatse to grant deliverance to the heir to the chieftainship of the Bamangwato, a large tribe living at Shoshong, to the north-east of Sechele's people. It was after a long conversation that the thing was settled. Macheng, the heir, who had been detained captive for sixteen years, was called, and Moselekatse addressing him said: "Macheng, man of Moffat, go with your father. We have arranged respecting you. Moffat will take you back to Sechele. That is my wish as well as his, that you should be in the first instance restored to the chief from whom you were taken in war. When captured you were a child; I have reared you to be a man."

The effect of this deliverance on the neighbouring tribes was very great. It occurred while Moffat was with Moselekatse, arranging for the settlement of the new missionaries. When he and his charge arrived at Sechele's town, on his way home, he was met by Sechele and the other chiefs of his tribe, who marched on in front, and led them to a kind of natural amphitheatre, where at least ten thousand of the people, in all their equipments of war, were assembled. Sechele commanded silence, and introduced the business of the meeting. Speaker followed speaker, in enthusiastic language giving expression to the joy they felt at seeing the chief of the Bamangwato return from captivity. In the course of his speech one said as follows:—

"Ye tribes, ye children of the ancients, this day is a day of marvel.... Now I begin to perceive that those who preach are verily true. If Moffat were not of God, he would not have espoused the cause of Sechele, in receiving his words, and delivering Macheng from the dwelling-place of the beasts of prey, to which we Bechwanas dared not approach. There are those who contend that there is nothing in religion. Let such to-day throw away their unbelief. If Moffat were not such a man, he would not have done what he has done, in bringing him who was lost—him who was dead—from the strong bondage of the mighty. Moselekatse is a lion; he conquered nations, he robbed the strong ones, he bereaved mothers, he took away the son of Kheri. We talk of love. What is love? We hear of the love of God. Is it not through the love of God that Macheng is among us to-day? A stranger, one of a nation—who of you knows its distance from us?—he makes himself one of us, enters the lion's abode, and brings out to us our own blood."

On reaching home, from his visit to the Matabele, Moffat found that the Livingstones were starting for the Zambesi, and were to call at the Cape on their way; also that a large party of new missionaries had been appointed to commence the new interior missions. The Moffats at once started for the Cape, and there met Dr. and Mrs. Livingstone and their companions. Once more the mother and daughter embraced each other, and as the latter had suffered much on the voyage, it was arranged that she should accompany the missionary party, and travel overland to the Zambesi.

At Cape Town Moffat also had the pleasure of welcoming his own son, the Rev. John Moffat, who was to proceed to the Matabele as a missionary, paid for out of Dr. Livingstone's private resources. Sir George Grey, Her Majesty's High Commissioner, warmly encouraged the proposed plans for extending Christianity and commerce to the interior tribes, and arranged with Robert Moffat for establishing a postal communication with the Zambesi viâ Kuruman.
