'Hearken' in the Bible

“Then it shall come about, because you listen to these judgments and keep and do them, that the Lord your God will keep with you the covenant and the [steadfast] lovingkindness which He swore to your fathers.

It shall come about that whoever will not listen to My words which he shall speak in My name, I Myself will require it of him [and there will be consequences].

Today you have [openly] declared the Lord to be your God, and that you will walk [that is, live each and every day] in His ways and keep His statutes, His commandments, and His judgments (precepts), and listen to His voice.
