Job 1:4 Meaning and Commentary

Job 1:4

And his sons went and feasted in their houses, everyone his
day
It appears by this that Job's sons were grown up to men's estate, that they were from him, and were for themselves, and carried on a separate business on their own accounts, and had houses of their own, and, perhaps, were married; and being at some distance from each other, they met by appointment at certain times in their own houses, and had friendly and family entertainments in turn; for such were their feasts, not designed for intemperance, luxury, and wantonness, for then they would not have been encouraged, nor even connived at, by Job; but to cherish love and affection, and maintain harmony and unity among themselves, which must be very pleasing to their parent; for a pleasant thing it is for any, and especially for parents, to behold brethren dwelling together in unity, ( Psalms 133:1 ) , besides, these feasts were kept, not in public houses, much less in houses of ill fame, but in their own houses, among themselves, at certain seasons, which they took in turn; and these were either at their time of sheep shearing, which was a time of feasting, ( 1 Samuel 25:2 1 Samuel 25:36 ) , or at the weaning of a child, ( Genesis 21:8 ) , or rather on each of their birthdays, which in those early times were observed, especially those of persons of figure, ( Genesis 40:20 ) , and the rather, as Job's birthday is called his day, as here, ( Job 3:1 ) ,

and sent and called for their three sisters to eat and to drink with
them;
not to make a feast in their turn, but to partake of their entertainment; which, as is commonly observed, showed humanity, kindness, tenderness, and affection in them to their sisters, to invite them to take part with them in their innocent and social recreations, and modesty in their sisters not to thrust themselves into their company, or go without an invitation; these very probably were with Job, and went to the feasts with his leave, being very likely unmarried, or otherwise their husbands would have been invited also.

Job 1:4 In-Context

2 And there are borne to him seven sons and three daughters,
3 and his substance is seven thousand sheep, and three thousand camels, and five hundred pairs of oxen, and five hundred she-asses, and a service very abundant; and that man is greater than any of the sons of the east.
4 And his sons have gone and made a banquet -- the house of each [in] his day -- and have sent and called to their three sisters to eat and to drink with them;
5 and it cometh to pass, when they have gone round the days of the banquet, that Job doth send and sanctify them, and hath risen early in the morning, and caused to ascend burnt-offerings -- the number of them all -- for Job said, `Perhaps my sons have sinned, yet blessed God in their heart.' Thus doth Job all the days.
6 And the day is, that sons of God come in to station themselves by Jehovah, and there doth come also the Adversary in their midst.
