He shall feed his flock like a shepherd: he shall gather the lambs with his arm, and carry them in his bosom, and shall gently lead those that are with young.

Clement Of Alexandria
AD 215
He calls us lambs, the Spirit by the mouth of Isaiah is an unimpeachable witness, using the figurative appellation of lambs, which are still more tender than sheep, to express simplicity.
