'Swelling' in the Bible

Though the waters thereof roar and be troubled, Though the mountains tremble with the swelling thereof. Selah

therefore this iniquity shall be to you as a breach ready to fall, swelling out in a high wall, whose breaking cometh suddenly in an instant.

For, uttering great swelling words of vanity, they entice in the lusts of the flesh, by lasciviousness, those who are just escaping from them that live in error;

These are murmurers, complainers, walking after their lusts (and their mouth speaketh great swelling words ), showing respect of persons for the sake of advantage.
