'Sworn' in the Bible

The Lord GOD hath sworn by his holiness, that, lo, the days shall come upon you, that he will take you away with hooks, and your posterity with fishhooks.

The Lord GOD hath sworn by himself, saith the LORD the God of hosts, I abhor the excellency of Jacob, and hate his palaces: therefore will I deliver up the city with all that is therein.

The LORD hath sworn by the excellency of Jacob, Surely I will never forget any of their works.
