Job 1:4

And his sons went and feasted . "Went and feasted" seems to mean "were in the habit of feastlng" (Rosenmuller, Lee). In their houses. Each had his own residence, and the residence was not a tent, but a" house." Job and his sons were not mere nomads, but belonged to the settled population. The same is implied by the "ploughing of the oxen" (verse 14), and indeed by Job's "yoke of oxen" in verse 3. Every one his day . Most commentators regard these feasts as birthday festivities. Each son in his turn, when his birthday arrived, entertained his six brothers. Others think that each of the seven brothers had his own special day of the week on which, he received his brothers at his table, so that the feasting was continuous. But this scarcely suits the context. And it is admitted that "his day" (in Job 3:1 ) means "his birthday." The celebration of birthdays by means of a feast was a very widespread custom in the East. And sent and called for their three sisters to eat and to drink with them. This by itself is sufficient to show that the feasts were occasional, not continuous. Constant absence of daughters, day after day, from the parental board is inconceivable.
