"Yet his days shall be an hundred and twenty years." God also would yet have patience with these people, if peradventure they would repent that his hand might not be upon them.
Ver. 4. "There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men, which were of old, men of renown."
"There were giants in the earth in those days." These words seem to be spoken, to shew us the hazards that Noah ran, while he preached the truth of God: He incurred the displeasure of the giants, which doubtless made all men tremble, and kept the whole world in awe. But Noah must engage the giants, he must not fear the face of a giant. This way God took also with Moses, and with his people of Israel, they must go to possess the land of the giants, a people high and tall as the cedars, a people of whom went that proverb, "Who can stand before the children of Anak?" (Deu 9:2). They must not be afraid of Og the king of Bashan, though his head be as high as the ridge of a house, and his bedstead a bedstead of iron (Deu 3:11).
This should teach us then not to fear the faces of men: no, not the faces of the mighty; not to fear them, I say, in the matters of God, though they should run upon us like a giant.
These giants I suppose were the children of Cain, because mentioned as another sort than those that were the fruit of their forbidden and ungodly communion: For he adds, "And also after that," or besides them, "when the sons of God came in unto the daughters of men, and they bare children to them, the same, [or they also] became mighty men which were of old, men of renown."
Then Noah found giants every where: Giants in the world, and giants in this confused communion. And thus it is at this day; we do not only meet with giants abroad, among the most ungodly and uncircumcised in heart, but even among those that seem to be of the religious, among them we also meet with giants; men mighty to oppose the truth, and very profound to make slaughter: But mark the advice of the Lord, "Fear not their fear, nor be afraid. Sanctify the Lord of hosts himself, [who is stronger than all the giants that are upon the face of the earth] and let him be your fear, and let him be your dread" (Isa 8:12,13).
"And when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men"; much like to the giants. The fruit therefore of ungodly communion is monstrous, and of a very strange complexion. They are like unto them that worshipped the Lord, and served their own gods also (2 Kings 17:24,41); or like to those of the church, of whom Nehemiah speaks, that had mixed themselves with the children of Ashdod, Ammon and Moab, whose children were a monstrous brood, that spake half the language of Ashdod, and could not speak the Jews' language (Neh 13:23,24).
By both these sorts of giants was faithful Noah despised, and his work for God condemned. In David's time also Goliath defied Israel, and so did his brethren also (1 Sam 17:10). Giants, the sons of the giant; but David and his servants must engage them, and fight them, though they were giants (1 Chron 20:4-8).
"Mighty men which were of old." Persecution therefore, or the appearance of the giants against the servants of God, is no new business; not a thing of yesterday, but of old, even when Noah did minister for God in the world. "There were giants in the earth in those days," to oppose him.
"Men of renown." Not for faith and holiness, but for some other high achievements, may be, mighty to fight, and to shed man's blood; or to find out arts, and the nature of things; both which did render them famous, and men to be noted in their place. Such kind of men might be Corah, Dathan, and their company also; yet they opposed Moses and Aaron, yea, God, his way and worship, and perished after an unheard of manner (Num 16:1,2). As also did the opposers of righteous Noah, in the day of the flood.
