Adam Clarke's Commentary on the Bible

Verse 37 (Psalms 106:37)

They sacrificed their sons and their daughters unto devils - See 2 Kings 16:3 ; Isaiah 57:5 ; Ezekiel 16:20 ; ezekiel Ezekiel 20:26 . That causing their sons and their daughters to pass through the fire to Moloch did not always mean they burnt them to death in the flames, is very probable. But all the heathen had human sacrifices; of this their history is full. Unto devils, לשדים lashshedim , to demons. Devil is never in Scripture used in the plural; there is but One devil, though there are Many demons.
