'Saith' in the Bible

Thus saith Jehovah: Though they be complete in number, and many as they be, even so shall they be cut down, and he shall pass away; and 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 into 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 shew the nations thy nakedness, and the kingdoms thy shame.
