This and many other verses in Scripture describe God as merciful and compassionate, slow to wrath, and plentiful in kindness (cf. Ps 103:8 ; James 5:11; 1 John 4:16). By contrast, numerous passages in the Bible reveal God as wrathful and vengeful. God told Moses, “You shall destroy all the peoples whom the Lord your God delivers over to you; your eye shall not pity them” (Deut. 7:16; cf. 1 Sam. 6:19; 15:2-3; Jer. 13:14; Heb. 12:29).
Lamentations 3:1 - 66
ESV - 1 I am the man who has seen affliction under the rod of his wrath. 2 He has driven and brought me into darkness without any light.
