'Hearken' in the Bible

According as we hearkened to Moses in all things, so will we hearken to thee; only may Jehovah thy God be with thee as he was with Moses.

but I would not hearken unto Balaam, and he blessed you expressly, and I delivered you out of his hand.

And the people said unto Joshua, Jehovah our God will we serve, and to his voice will we hearken.
