From a wicked neighbour, see that thou keep aloof, and spend not much of thy time among the peoplewho speak ill of their brother-man; be not as the fly that is always seeking sick and wounded places; and tell not of the faults and failings of those about thee.
Take no one to wife unworthy to be thy life’s partner, and keep thy sons close to the study of Divine things. Dare not to rejoice when thine enemy comes to the ground; but give him food when he hungers. Be on thy guard lest thou give pain ever to the widow and the orphan; and beware lest thou ever set thyself up to be both witness and judge against an other.
Never enter thy house with abrupt and startling step, and bear not thyself so that those who dwell under thy roof shall dread when in thy presence. Purge thy soul of angry passion, that inheritance of fools; love wise men, and strive to know more and more of the works and the ways of the Creator.
ELIEZER BEN ISAAC, 1050.
II
BE not ready to quarrel; avoid oaths and passionate adjurations, excess of laughter and outbursts of wrath; they disturb and confound the reason of man. Avoid all dealings wherein there is a lie; utter not the name of God superfluously, or in places dirty or defiled.
Cut from under thee all mere human supports, and make not gold the foremost longing of thy life; for that is the first step to idolatry. Rather givemoney than words; and as to ill words, see that thou place them in the scale of understanding before they leave thy lips.
What has been uttered in thy presence, even though not told as secret, let it not pass from thee to others. And if one tell thee a tale, say not to him that thou hast heard it all before. Do not fix thine eyes too much on one who is far above thee in wealth, but on those who are behind thee in worldly fortune.
Put no one to open shame; misuse not thy power against any one; who can tell whether thou wilt not some day be powerless thyself?
