'Countless' in the Bible

And they blessed Rebekah and said to her, "You [are] our sister; may you become countless thousands; and may your offspring take possession of the gate of his enemies."

And they piled them [in] countless heaps, and the land stank.

And when it rested he would say, "Return, Yahweh, to the countless thousands of Israel."

For many slain she has laid low, and countless [are] all of her killings.
