Altars (Hebrew: מִזְבֵּחַ, mizbeaḥ, "a place of slaughter or sacrifice") in the Hebrew Bible were typically made of earth (Exodus 20:24) or unwrought stone (20:25). Altars were generally erected in conspicuous places (Genesis 22:9; Ezekiel 6:3; 2 Kings 23:12; 16:4; 23:8). The first altar recorded in the Hebrew Bible is that erected by Noah (Genesis 8:20). Altars were erected by Abraham (Genesis 12:7; 13:4; 13:18;22:9), byIsaac (Genesis 26:25), by Jacob (33:20; 35:1–3), by Moses (Exodus 17:15), and by Saul (1 Samuel 14:35).
