'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 cause my people to err, that bite with their teeth, and cry, Peace! but whoso putteth not into their mouths they prepare war against him:

In that day, saith Jehovah, will I assemble her that halteth, and I will gather her that is driven out, and her that 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 I will destroy thy chariots.

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