The LORD thy God in the midst of thee is mighty; he will save, he will rejoice over thee with joy; he will rest in his love, he will joy over thee with singing.
The Lord thy God in the midst of thee ... he will rejoice over thee with joy - even "as the bridegroom rejoiceth over the bride" (Isaiah 62:5); so will the Lord "rejoice in Jerusalem, and joy in His people" (Isaiah 65:19).
He will rest in his love - content with it as His supreme delight, even as "there is joy in heaven ... in the presence of the angels of God ... over one sinner that repenteth" (Luke 15:7; Luke 15:10) (Calvin). Or, He shall be silent [from chaarash, to be silent] - namely, as to thy faults, not "imputing" them to thee (Maurer). (Psalms 32:2; Exodus 33:16.) I prefer explaining it of that calm silent joy, in the possession of the object of one's love, too great for words to express; just as God, after the six days of creation, rested with silent satisfaction in His work, because "behold, it was very good" (Genesis 1:31; Genesis 2:2). So the parallel clause, by contrast, expresses the joy, not kept silent, as this, but uttered in good" (Genesis 1:31; Genesis 2:2). So the parallel clause, by contrast, expresses the joy, not kept silent, as this, but uttered in "singing."
