Which I have reserved for the time of trouble: this line begins with a relative particle translated as which, connecting verse 23 to verse 22. God has kept snow and hail for the time of trouble.

The day of battle and war makes specific what is meant by the parallel time of trouble in line a. God threw hailstones down on the Amorites in Joshua 10.11 as they fled from Israel. Battle and war appear to be a fixed pair of expressions. No attempt is made to distinguish these as different kinds of events. In some languages it may be necessary to adjust verse 23 to say, for example, “I have kept them stored up in case of troubles when there is a war” or “I keep them stored for the times when people fight and have wars.”
