'Reserves' in the Bible

‘They do not say in their heart,“Let us now fear and worship the Lord our God [with profound awe and reverence],Who gives rain in its season,Both the autumn and the spring rain,Who keeps for usThe appointed weeks of the harvest.”

The Lord is a jealous and avenging God [protecting and demanding what is rightfully and uniquely His];The Lord avenges and He is full of wrath.The Lord takes vengeance on His adversaries,And He reserves wrath for His enemies.
