For if ye turn again unto the Lord,.... To the fear or worship of the Lord, as the Targum:
your brethren and your children shall find compassion before them that lead them captive, so that they shall come again into this land; who had been carried away by Tiglathpileser, see Psalms 106:46,
for the Lord your God is gracious and merciful; so he had proclaimed his name, as they must know, Exodus 34:6,
and will not turn away his face from you; in wrath and anger; or withdraw his Shecaniah from you, as the Targum; his gracious and glorious presence:
if ye return unto him; his fear and worship, as the same paraphrase.
