Like a shepherd He will tend His flock, In His arm He will gather the lambs And carry them in His bosom; He will gently lead the nursing ewes. (Isaiah 40:11)
A picture of God’s omnipotence. The same arm that powerfully scatters the Jews all over the earth in judgment is to overcome Israel’s oppressors and to tenderly feed and lead his flock
In that part of the world especially, shepherding involved constant hands-on care from shepherd to sheep. Middle Eastern flocks (even today) aren’t generally herded by dogs as in most Western sheep ranching; they are led by the shepherd. In other words, he leads by serving them, not by driving them.
