Make a joyful noise unto God, all ye lands:
All lands — Ye people of all nations. He invites the Gentile world, to the contemplation and celebration of God's works.
 He turned the sea into dry land: they went through the flood on foot: there did we rejoice in him.
We — Our nation, or our ancestors, in whose loins we then were.
 For thou, O God, hast proved us: thou hast tried us, as silver is tried.
Proved us — As it were in a burning furnace; and with a design to purge out our dross.
 Thou broughtest us into the net; thou laidst affliction upon our loins.
Net — Which our enemies laid for us.
 Thou hast caused men to ride over our heads; we went through fire and through water: but thou broughtest us out into a wealthy place.
To ride — To use us like slaves.
 I will offer unto thee burnt sacrifices of fatlings, with the incense of rams; I will offer bullocks with goats. /*Selah*/.
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.
 If I regard iniquity in my heart, the Lord will not hear me:
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.
