'Let Us' in the Bible

So let us keep our feast, not with old yeast nor with the yeast of vice and wickedness, but with the bread of purity and truth without the yeast.

Let us stop practicing immorality, as some of them did, and on one day twenty-three thousand fell dead.

Let us stop trying the Lord's patience, as some of them did, and for it were destroyed by the snakes.

If from merely human motives I have fought wild beasts here in Ephesus, what profit will it be to me? If the dead are never raised at all, "Let us eat and drink, for tomorrow we shall be dead."

and as we have reflected the likeness of him who was made of dust, let us also reflect the likeness of the Man from heaven.
