'Let Us' in the Bible

And the king saith unto Absalom, 'Nay, my son, let us not all go, I pray thee, and we are not too heavy on thee;' and he presseth on him, and he hath not been willing to go, and he blesseth him.

And David saith unto Gad, 'I have great distress, let us fall, I pray thee, into the hand of Jehovah, for many are His mercies, and into the hand of man let me not fall.'
