Charles Ellicott Commentary Psalms 106:38

"And shed innocent blood, Even the blood of their sons and of their daughters, Whom they sacrificed unto the idols of Canaan; And the land was polluted with blood." — Psalms 106:38 (ASV)

Innocent blood. —Human sacrifice, and especially that of children, was a Canaanite practice. It seems to have been inherent in Phoenician custom, for Carthage was, two centuries after Christ, notorious for it. (See Sil. Ital., iv. 767.)
