He that exalteth his gate - In different parts of Palestine they are obliged to have the doors of their courts and houses very low, not more than three feet high, to prevent the Arabs, who scarcely ever leave the backs of their horses, from riding into the courts and houses, and spoiling their goods. He, then, who, through pride and ostentation, made a high gate, exposed himself to destruction; and is said here to seek it, because he must know that this would be a necessary consequence of exalting his gate. But although the above is a fact, yet possibly gate is here taken for the mouth; and the exalting of the gate may mean proud boasting and arrogant speaking, such as has a tendency to kindle and maintain strife. And this interpretation seems to agree better with the scope of the context than the above.
He that exalteth his gate - i. e., Builds a stately house, indulges in arrogant ostentation.
