Charles Spurgeon Commentary Jonah 2:8

"They that regard lying vanities Forsake their own mercy." — Jonah 2:8 (ASV)

If you trust anywhere but in God, you will run away from your own mercy. God is the only really merciful One who can always help you; but if you trust in your own righteousness, if you trust in priestcraft, if you trust in any superstition, you are observing lying vanities, and forsaking your own mercy. God is the source of your mercy; do not run away from him to anyone or anything else.
