'Behaving' in the Bible

But if anyone thinks he is behaving dishonorably concerning his virgin, if she is past her prime and it ought to be thus, let him do what he wishes. He does not sin. Let them marry.

but we have renounced shameful hidden things, not behaving with craftiness or adulterating the word of God, but with the open proclamation of the truth commending ourselves to every person's conscience before God.

now I ask [when I] am present [that I will] not [need] to be bold with the confidence [with] which I propose to show boldness toward some who consider us as behaving according to the flesh.
