'Saith' in the Bible

I will utterly take away everything from off the face of the ground, saith Jehovah:

I will take away man and beast; I will take away the fowl of the heavens and the fishes of the sea, and the stumbling-blocks with the wicked, and I will cut off mankind from off the face of the ground, saith Jehovah.

And in that day, saith Jehovah, there shall be the noise of a cry from the fish-gate, and a howling from the second quarter, and a great crashing from the hills.

Therefore, as I live, saith Jehovah of hosts, the God of Israel, Moab shall certainly be as Sodom, and the children of Ammon as Gomorrah, a possession of nettles, and salt-pits, and a perpetual desolation; the remnant of my people shall spoil them, and the residue of my nation shall possess them.

Therefore wait ye for me, saith Jehovah, until the day that I rise up to the prey; for my determination is to assemble the nations, that I may gather the kingdoms together, to pour upon them mine indignation, all my fierce anger: for all the earth shall be devoured with the fire of my jealousy.

At that time will I bring you, yea, at the time that I gather you; for I will make you a name and a praise, among all the peoples of the earth, when I shall turn again your captivity before your eyes, saith Jehovah.
