'Letting' in the Bible

Continue to follow and be submissive to your leaders, since they are watching over your souls as those who will have to give a word of explanation. By doing this, you will be letting them carry out their duties joyfully, and not with grief, for that would be harmful for you.

just as Sarah obeyed Abraham and called him lord. You have become her daughters by doing good and by not letting anything terrify you.
