And rend your heart, and not your garments, and turn unto the LORD your God: for he is gracious and merciful, slow to anger, and of great kindness, and repenteth him of the evil.
And rend your heart, and not your garments - let there be the inward sorrow of heart, and not the mere outward manifestation of it by 'rending the garment' (Joshua 7:6).
He is gracious and merciful. The Hebrew words are intensive, very gracious and very merciful. The attributes of God here are taken from the Pentateuch (Exodus 34:6-7, "The Lord, the Lord God, merciful and gracious, long-suffering, and abundant in goodness and truth, keeping mercy for thousands, forgiving iniquity and transgression and sin").
Of great kindness - elsewhere rendered, as in Exodus 34:6, "abundant in goodness" х rab (H7227) checed (H2617)]. He ... repenteth him of the evil - the calamity which He had threatened against the impenitent.
