'Hearken' in the Bible

according to all that we hearkened unto Moses in, so we hearken unto thee; surely Jehovah thy God is with thee as He hath been with Moses.

and saith unto them, 'Ye -- ye have kept the whole of that which Moses, servant of Jehovah, commanded you, and ye hearken to my voice, to all that I have commanded you;

and I have not been willing to hearken to Balaam, and he doth greatly bless you, and I deliver you out of his hand.

And the people say unto Joshua, 'Jehovah our God we serve, and to His voice we hearken.'
