'Sand of the Sea' in the Bible

Their widows have become multiplied to me, beyond the sand of the seas, I have brought against them - upon the mother of young men - the spoiler in the broad noon, - I have let fall upon her suddenly, excitement and terrors.

As, the host of the heavens, cannot be recorded, Nor the sand of the sea, be measured, So, will I multiply, The seed of David my servant, And the Levites who attend upon me.
