John Wesley’s NotesPsalms 66

All lands - Ye people of all nations. He invites the Gentile world, to the contemplation and celebration of God's works.

We - Our nation, or our ancestors, in whose loins we then were.

Proved us - As it were in a burning furnace; and with a design to purge out our dross.

Net - Which our enemies laid for us.

To ride - To use us like slaves.

I will go - One speaks in the name of all the rest. Incense - With the fat of rams, which is no less pleasing to God than incense.

Iniquity - Any sin. In heart - If my heart had been false to God, although I might have forborne outward acts. If I had been guilty of that, by heart was set upon sin, or I desired only that which I resolved in my heart to spend upon my lusts.
