'Saith' in the Bible

Thus saith Jehovah: Though they be in full strength, and likewise many, even so shall they be cut down, and he shall pass away. Though I have afflicted thee, I will afflict thee no more.

Behold, I am against thee, saith Jehovah of hosts, and I will burn her chariots in the smoke, and the sword shall devour thy young lions; and I will cut off thy prey from the earth, and the voice of thy messengers shall no more be heard.

Behold, I am against thee, saith Jehovah of hosts, and I will uncover thy skirts upon thy face; and I will show the nations thy nakedness, and the kingdoms thy shame.
