Job 1:4

“And his sons went and feasted in their houses, everyone his day, etc.] 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…”

“every one his day--namely, the birthday (Job 3:1). Implying the love and harmony of the members of the family, as contrasted with the ruin which soon broke up such a scene of happiness. The sisters are specified, as these feasts were not for revelry, which would be inconsistent with the presence of sisters. These latter were invited by the brothers, though they gave no invitations in return.”

“And his sons went and feasted in their houses - Dr. Good renders this, “and his sons went to hold a banquet house.” Tindal renders it, “made bankertea.” The Hebrew means, they went and made a “house-feast;” and the idea is, that they gave an entertainment in their dwellings, in the ordinary way in which such entertainments were made.

He, though a pious…”

“Feasted - To testify and maintain their brotherly love. His day - Each his appointed day, perhaps his birth - day, or the first day of the month. Job 1:5”

“sent and called: Psa 133:1; Heb 13:1 Job 1:5”

“4, 5 And his sons went and feasted in the house of him whose day it was, and sent and called for their sisters to eat and drink with them. And it happened, when the days of their feasting were gone about, that Job sent and sanctified them, and rose up early in the morning, and offered burnt-offerings according to the number of them all: for Job said, I may be that my sons have sinned, and dismissed God from their hearts. Thus did Job continually. The subordinate facts precede, Job 1:4, in perff.; the chief fact follows, Job 1:5, in fut. consec. The perff. describe, according to Ges. 126, 3, that which has happened repeatedly in the past, as e.g., Rut 4:7; the fut. consec. the customary act…”
