'Obey' in the Bible

If a man sins against a man, then God can intercede for him. But if a man sins against Yahweh, who can intercede for him?" But they did not {obey} their father, because Yahweh wanted to kill them.

Then Samuel said, "Is there [as much] delight for Yahweh in burnt offerings and sacrifices as [there is] in {obeying} Yahweh? Look! {To obey} [is] better than sacrifice; to give heed than the fat of rams.

Because you {did not obey} Yahweh and did not carry out the fierce anger of his {wrath} against Amalek, therefore Yahweh has done this thing to you today.
