Let rumours be, when did not rumours fly? Tennyson.

Let sleeping dogs lie. Sc. Pr.

Let still the woman take / An elder than herself; so wears she to him, / So sways she level in her husband's heart; / For, boy, however we do praise ourselves, / Our fancies are more giddy and unfirm, / More longing, wavering, sooner lost and worn / Than women's are. Twelfth Night, ii. 4.

Let such teach others who themselves excel, / 40 And censure freely who have written well. Pope.

Let that which is lost be for God. Sp. Pr.

Let the angry person always have the quarrel to himself. Rev. John Clark.

Let the best horse leap the hedge first. Pr.

Let the cobbler stick to his last. Pr.

Let the dainty rose awhile / Her bashful fragrance 45 hide; / Rend not her silken veil too soon, / But leave her, in her own soft noon, / To flourish and abide. Keble.

Let the dead bury their dead, i.e., let the spiritually dead bury the bodily dead. Jesus.
