“And the LORD was with Judah; and he drave out the inhabitants of the mountain; but could not drive out the inhabitants of the valley, because they had chariots of iron.”
King James Version (KJV)
Matthew Henry's Concise Commentary
1:9-20 The Canaanites had iron chariots; but Israel had God on their side, whose chariots are thousands of angels, Ps 68:17. Yet they suffered their fears to prevail against their faith. About Caleb we read in Jos 15:16-19. The Kenites had settled in the land. Israel let them fix where they pleased, being a quiet, contented people. They that molested none, were molested by none. Blessed are the meek, for they shall inherit the earth.
“That thy foot may be dipped in the blood of thine enemies, and the tongue of thy dogs in the same.”
