'Heed' in the Bible

But Jehu took no heed to walk in the law of Jehovah the God of Israel with all his heart; he departed not from the sins of Jeroboam, who made Israel to sin.

neither will I any more cause the foot of Israel to wander away from the land that I gave their fathers; if they will only take heed to do according to all that I have commanded them, and according to all the law that my servant Moses commanded them.
