'Saith' in the Bible

Therefore thus saith Jehovah: Behold, against this family do I devise an evil, from which ye shall not remove your necks, neither shall ye walk haughtily; for it is an evil time.

Thus saith Jehovah concerning the prophets that make my people to err; that bite with their teeth, and cry, Peace; and whoso putteth not into their mouths, they even prepare war against him:

In that day, saith Jehovah, will I assemble that which is lame, and I will gather that which is driven away, and that which I have afflicted;

And it shall come to pass in that day, saith Jehovah, that I will cut off thy horses out of the midst of thee, and will destroy thy chariots:

Hear ye now what Jehovah saith: Arise, contend thou before the mountains, and let the hills hear thy voice.
