'Heed' in the Bible

Therefore we ought to give the more earnest heed to the things which we have heard, lest at any time we should let them slip.

Take heed, brethren, lest there be in any of you an evil heart of unbelief, in departing from the living God.

For Good News has been brought to us as truly as to them; but the message they heard failed to benefit them, because they were not one in faith with those who gave heed to it.

And having been made perfect [uniquely equipped and prepared as Savior and retaining His integrity amid opposition], He became the source of eternal salvation [an eternal inheritance] to all those who obey Him,

By faith [with confidence in God and His word] Noah, being warned by God about events not yet seen, in reverence prepared an ark for the salvation of his family. By this [act of obedience] he condemned the world and became an heir of the righteousness which comes by faith.

See to it that you do not refuse [to listen to] Him who is speaking [to you now]. For if those [sons of Israel] did not escape when they refused [to listen to] him who warned them on earth [revealing God’s will], how much less will we escape if we turn our backs on Him who warns from heaven?
