Job 1:4

And his sons went and feasted [in their] houses, every one his day; and sent and called for their three sisters to eat and to drink with them.

Ver. 4. And his sons went and feasted in their houses] They were of ripe years; and although unmarried, yet had they their several houses to dwell in. This declareth not only the wealthiness of the family, but also the good order and government thereof, as Beza observeth. Their orderly intercourse of friendly feasting one another shows their mutual love, concord, and agreement, by this means testified and increased. For wine hath (as one long since observed) ελκυστικον τι προς φιλιαν, an attractive power in it to make and keep friendship; and from the drinking of wine the word here used for a feast hath its denomination (משׁחה .) We may not think that they did thus every day, as that glutton the Gospel; or that in their banquets they used any excess, as the manner is of riotous and intemperate persons; for they had been better bred, and they observed this order with great modesty and discretion. They went and feasted; that is, they did it readily and cheerfully, that brotherly love might continue; for - Fratrum quoque gratia rara est. Favour has been rare between bothers. The devil doth what he can to cast a bone between brethren, to make those that should love most dearly to hate one another most deadly. See this exemplified in Cain and Abel, Esau and Jacob, Joseph and his brethren, Joram and his, Romulus and Remus, Caracalla and Geta, Robert and Rufus, the two sons of William the Conqueror, Polynices and Eteocles, &c. And when such are once out, "A brother offended" (saith Solomon) "is harder to be won than a strong city: and their contentions are like the bars of a castle," which, being strong, will neither bow nor yield, Proverbs 18:19. All good means, therefore, must be used to prevent them, and to preserve that amity and unity which the psalmist doth so magnify, Psalms 133:1,3, and concludeth, that there God commandeth the blessing, and life for evermore; that is, constant happiness perpetuated in and by a blessed posterity. The number of two hath been accounted accursed, because it was the first that departed from unity.

And sent and called for their three sisters] That their number and amity might be complete. This was no small joy to Job, that his children were so kind one to another. It is reckoned as a piece of his happiness; that which was denied to Abraham and Isaac (though fathers only of two children), to Jacob also, and Samuel, and David, Constantine the Great, and many others; whose children, through ambition, pride, covetousness, envy, evil surmises, &c., have been at odds, nay, at deadly feud among themselves. Beza upon these words observeth, that the sisters kept not with their brethren, but had their dwelling apart from them; which was both more seemly and more safe, as also more agreeing with maidenly shamefacedness. Neither is it said, that Job's sons sent for any other women; yea, the sisters came not over boldly to the banquets of their brethren, although they knew them to be men of a sober and honest disposition.
