'Inadequate' in the Bible

The Lord said to Moses, “Is the Lord’s hand (ability, power) limited (short, inadequate)? You shall see now whether My word will come to pass for you or not.”

The descendants of Joseph said, "The whole hill country is inadequate for us, and the Canaanites living down in the valley in Beth Shean and its surrounding towns and in the Valley of Jezreel have chariots with iron-rimmed wheels."
