Matthew Poole and continuators on Lamentations 3:32

32 But though he cause grief, yet will he have compassion according to the multitude of his mercies .

But though as a prudent Parent he may see reason to cause grief in, and to afflict his own people, yet as a tender good Father, that pitieth his children in Misery he will have compassion upon them, having not onely mercies, but a multitude or abundance of Mercies.
