Jerome : (Verse 10.) Because you have forgotten your God and have not remembered your powerful helper. These things, he says, you will endure, O Israel, because you have forsaken your God, who has freed you from Egypt, who has subjected enemy nations to you; and you have not remembered your helper. Therefore you will plant a faithful plantation, and you will sow a foreign seed. This should be read more closely and ironically. For, he says, you have forgotten your God and Savior, and you have not remembered your strong helper: should you therefore plant a faithful plantation, and not rather sow a foreign seed, which the enemy will snatch away? Or certainly like this: you have founded my sons, who are born from the stock of my people, in the land, in order to make them foreign and wicked. — Commentary on Isaiah
