Shall remember - So as to turn unto me. Broken - I am much grieved. Whorish heart - Idolatrous hearts depart from God, as an adulterous wife departs from her husband. Loath - With a mixture of grief towards God, of indignation against themselves, and abhorrence of the offence.
In vain - Either without cause, the sufferers gave him just cause to pronounce that evil; or without effect. Their sins where the cause, and their destruction is the effect of their sufferings.
Wilderness - The horrid wilderness of Moab. Therein the fiery serpents so much annoyed Israel. Accordingly the land of Canaan is at this day one of the most desolate countries in the world.
