Birth-day
The observance of birth-days was common in early times (Job 1:4, Job 1:13, Job 1:18). They were specially celebrated in the land of Egypt (Gen 40:20). There is no recorded instance in Scripture of the celebration of birth-days among the Jews. On the occasion of Herod’s birth-day John the Baptist was beheaded (Matt 14:6).
