Verse 4
Come out of her, my people - These words appear to be taken from Isa 48:20; Jer 1:8; Jer 51:6, Jer 51:45. The poet Mantuanus expresses this thought well: -
Vivere qui sancte cupitis, discelite; Romae
Omnia quum liceant, non licet esse bonum. "Ye who desire to live a godly life, depart; for, although all things are lawful at Rome, yet to be godly is unlawful.
