My people hath been lost sheep: their shepherds have caused them to go astray, they have turned them away on the mountains: they have gone from mountain to hill, they have forgotten their restingplace.
My people hath been lost sheep - (Isaiah 53:6, "All we like sheep have gone astray").
They have turned them away on the mountains - whereon they sacrificed to idols (Jeremiah 2:20; Jeremiah 3:6; Jeremiah 3:23).
They have forgotten their resting-place - the resting-place for the "sheep;" continuing the image, Yahweh Jesus is the resting-place of His sheep (Matthew 11:28). They rest in His "bosom," wherein He "carries" them (Isaiah 40:11). Also His temple at Zion is their "rest," because it is His (Psalms 132:8; Psalms 132:14).
