John Wesley on Matthew 3:10

But the axe also already lieth - That is, there is no room for such idle pretences. Speedy execution is determined against all that do not repent. The comparison seems to be taken from a woodman that has laid down his axe to put off his coat, and then immediately goes to work to cut down the tree. This refers to the wrath to come in verse 7, Mt 3:7. Is hewn down - Instantly, without farther delay.
