“I desire mercy and not sacrifice.”
On at least two occasions the Lord applied these words first spoken by Hosea in 6:6. Both speakers expressed what was appropriate to circumstances that prevailed in their time.
Hosea was responding to his nation’s blindness regarding the Lord’s overriding purpose in delivering Israel from slavery, giving them the law through Moses along with instructions to guide them in offering sacrifices. They were to be a completely different people, their manner of life superior to what was going on in various nations around them. Those nations had their sacrifices and offered them to ward off punishment from the god or gods they offended.
