FIRSTBORN

Term used in the Bible to describe a family’s oldest son or daughter (Gn 22:21; 29:26). Israel was called God’s firstborn because of that nation’s miraculous beginning and special deliverance out of Egypt (Gn 17:5, 15-16; Ex 4:22). As God’s firstborn, Israel had unique privileges over all other nations. Gentiles were “blessed” only in relation to their kindness to Israel (Gn 12:3; Ex 19:6; Dt 4:5-8). The prophet Isaiah foresaw a day when Israel would have a double portion of inheritance (Is 61:7). Thus, being firstborn implies priority or preeminence, as well as an inheritance.

The expression “first-born of the poor,” (Is 14:30, rsv) means one who is supremely poor, the poorest of the poor. Another figurative expression, “first-born of death” (Jb 18:13, rsv), implied that Job’s disease was fatal.

Because God delivered Israel’s firstborn sons from death in Egypt, he expected each firstborn to be sanctified to him (Ex 11:4-7; 13:12). The first male child was a representative of the entire offspring (Gn 49:3; Ex 22:29; Nm 3:13). The firstborn of all animals used in sacrifice was to be sanctified to the Lord (Ex 13:2, 15).

Firstborn and Redemption

The firstborn of every tribe except Levi’s was to be redeemed by a sum not to exceed five shekels (Nm 18:15-16). Redemption implied a previous bondage and was to remind Israel of their redemption from bondage in Egypt (Ex 13:2-8).

The firstborn of ritually clean animals was devoted to the Lord. It was brought to the tabernacle (or later, the temple) within a year from the eighth day after birth. This animal was then sacrificed and its blood sprinkled on the altar. The meat of the sacrificed animal was for the priests (Ex 13:13; 22:30; cf. Nm 18:17). The firstborn of unclean animals could be redeemed with an addition of one-fifth of the value as determined by the priest. If not redeemed, these animals were sold, exchanged, or destroyed by the priests (Lv 27:27). The colt of an ass was to be redeemed with a lamb (Ex 13:13). If not redeemed, it was to be killed. Meat from unclean animals was not eaten.

Firstborn and Birthright

The firstborn acted as priest of the family in the father’s absence or death. Esau and Reuben are both examples (Gn 27:19, 32; 1 Chr 5:1-2). This position of the firstborn ceased when the priesthood was committed to Levi’s tribe (Nm 3:12-13). All the firstborn of succeeding generations had to be redeemed. The redemption money became part of the Levites’ yearly income (8:17; 18:16).

A double portion of the family inheritance was the right of the firstborn. This protected the firstborn when there was a polygamous marriage. The son of a favorite wife could not take the place of the first son born of the household (Dt 21:17).

The title “firstborn” is applied to Christ (Lk 2:7; Rom 8:29; Col 1:15, 18; Heb 1:6; Rv 1:5). It stresses Christ’s preeminence over all because he was the first to rise from the dead. As firstborn, Christ is heir of all things (Heb 1:2) and the head of the church (Eph 1:20-23; Col 1:18, 24; Heb 2:10-12).
