The Detestable Practice of Divinely Sanctioned Child Sacrifice in the Bible
Child sacrifice was something that several Biblical people either did, or assisted others in doing so. Abraham was not morally repulsed by the command itself (Genesis 22). Then there is Jepthah who probably sacrificed his daughter because of a stupid vow (Judges 11)
It was a problem for King Josiah ( II King 23:10), for Jeremiah (Jeremiah 7:30-31; 19:3-5; 32:35), and Ezekiel (Ezekiel 16:20-21; 20:25-26, 30-31).
The prophet Micah wonders if he should sacrifice his oldest son “as a sin offering” (6:6-8). Child sacrifice to foreign gods was so prevalent that it’s named as one of the major reasons why God sent the Babylonians to conquer Israel and forcibly take many of them as captives (II Kings 17:16-18).
We even read where the King of Moab sacrificed his son which caused the Israelites to retreat in defeat.
