Assyria can't save us. We won't ride on horses; Neither will we say any more to the work of our hands, 'Our gods!' For in you the fatherless finds mercy."
What follows, On a horse we shall not mount, may be explained in two ways; — as though they said, that they would no longer be so mad as to be proud of their own power, or consider themselves safe because they were well furnished with horses and chariots; — but the clause may be more simply explained, as meaning, that they would not as before wander here and there to procure for themselves auxiliaries; We shall not then mount a horse, but continue quiet in our country; and this sense seems more appropriate. I do not then think that the Prophet brings forward any new idea, but I read the two sentences conjointly, The Assyrian shall not save us, we shall not then mount on a horse, that is, that we may ride in haste; for they had wearied themselves before with long journeys: as soon as any danger was at hand, they went away afar off into Assyria to seek help, when God commanded them to remain quiet.
