Genesis 29:14

14.And he abode with him the space of a month. Though Laban did not doubt that Jacob was his nephew by his sister, he nevertheless puts his character to trial during a month, and then treats with him respecting wages. Hence may be inferred the uprightness of the holy man; because he was not idle while with his uncle, but employed himself in honest labors, that he might not in idleness eat another’s bread for nothing; hence Laban is compelled to acknowledge that some reward beyond his mere food was due to him. When he says, “Because thou art my brother, shouldest thou therefore serve me for nought?” his meaning may be twofold; either that it would be excessively absurd and unjust to defraud a relation of his due reward, for whom he ought to have greater consideration than for any stranger; or that he was unwilling to exact gratuitous service under the color of relationship. This second exposition is the more suitable, and is received nearly by the consent of all. For they read in one connected sentence, “Because thou art my brother, shalt thou therefore serve me for nought?” Moreover, we must note the end for which Moses relates these things. In the first place, a great principle of equity is set before us in Laban; inasmuch as this sentiment is inherent in almost all minds, that justice ought to be mutually cultivated, till blind cupidity draws them away in another direction. And God has engraven in man’s nature a law of equity; so that whoever declines from that rule, through an immoderate desire of private advantage, is left utterly without excuse. But a little while after, when it came to a matter of practice, Laban, forgetful of this equity, thinks only of what may be profitable to himself. Such an example is certainly worthy of notice, for men seldom err in general principles, and therefore, with one mouth, confess that every man ought to receive what is his due but as soon as they descend to their own affairs, perverse self-love blinds them, or at least envelopes them in such clouds that they are carried in an opposite course. Wherefore, let us learn to restrain ourselves, that a desire of our own advantage may not prevail to the sacrifice of justice. And hence has arisen the proverb, that no one is a fit judge in his own cause, because each, being unduly favorable to himself, becomes forgetful of what is right. Wherefore, we must ask God to govern and restrain our affections by a spirit of sound judgment. Laban, in wishing to enter into a covenant, does what tends to avoid contentions and complaints. The ancient saying is known, “We should deal lawfully with our friends, that we may not afterwards be obliged to go to law with them.” For, whence arise so many legal broils, except that every one is more liberal towards himself, and more niggardly towards others than he ought to be? Therefore, for the purpose of cherishing concord, firm compacts are necessary, which may prevent injustice on one side or the other.
