'Heed' in the Bible

For this reason we ought to pay the more earnest heed to the things which we have heard, for fear we should drift away from them.

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.

Through faith Noah, being divinely taught about things as yet unseen, reverently gave heed and built an ark for the safety of his family, and by this act he condemned the world, and became an heir of the righteousness which depends on faith.
