Even as a shepherd that feedeth his flock, That gathereth the lambs in his arm, And carrieth them in his bosom, And gently leadeth those that give suck.

Like a shepherd [who] tends his flock Like a shepherd who tends his flock; with his arm he gathers lambs, and he carries them in his bosom.
Ibn Ezra on Isaiah
And carry them in his bosom. Namely those that cannot walk.
Rashi on Isaiah
the nursing ones he leads [Jonathan renders:] The nursing ones he leads gently, the nursing sheep.
