First-born, Sanctification of the

The sanctification of the first-born is closely related to but distinct from their redemption. All first-born males of both humans and animals were declared holy to the LORD — set apart as his special possession — on the basis of the Passover event. This sanctification established a prior claim that God held over the first-born, a claim that redemption payments acknowledged rather than canceled.

The principle appears first in God's demand on the first-born of Israel in Egypt (Exodus 11:4-5; 13:2): by striking all first-born of Egypt and passing over Israel's, God demonstrated his ownership of life and his covenantal protection of his people. The first-born thus bore a kind of sacred status — set apart, belonging to God — that the rest of Israel did not share in the same way. Abel's offering of the "firstlings" of his flock (Genesis 4:4) is read in this light as an anticipation of the principle, offering to God what was most sacred. The Levites' service as substitutes for the sanctified first-born of all Israel completed the institutionalization of this principle in the Mosaic system.
