In Bible times, the firstborn son of a family was held in great honor (Genesis 49:3; Exodus 11:5; 34:19; Numbers 3:40; Psalm 89:27; Jeremiah 31:9).
Katika nyakati za Biblia, mzaliwa wa kwanza wa familia aliheshika pakubwa sana (Mwanzo 49:3 "katika mwanzo na Mungu."; Kutoka 11:5; 34:19 na Hesabu 3:40, Zaburi 89:27; Yeremia 31:9).
