'Let Us' in the Bible

So then, let us be keeping the feast, not with old leaven, nor with leaven of baseness and wickedness, - but with the unleavened bread of sincerity and truth.

Neither let us commit fornication, as, some of them, committed fornication, and there fell, in one day, three and twenty thousand;

Neither let us be putting the Lord to the test, as, some of them, put him to the test, and, by the serpents, were perishing;

If, after the manner of men, I have fought with wild-beasts at Ephesus, what, to me, the profit? If the dead are not raised, Let us eat and drink, for, tomorrow, we die.

And, even as we have borne the image of the man of earth, let us also bear the image of the man of heaven.
