'Hearken' in the Bible

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

Whosoever he be that shall rebel against thy commandment, and shall not hearken unto thy words in all that thou commandest him, he shall be put to death: only be strong and of good courage.

but I would not hearken unto Balaam; therefore he blessed you still: so I delivered you out of his hand.

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