'Sand' in the Bible

Do you not fear Me?This is the Lord’s declaration.Do you not tremble before Me,the One who set the sand as the boundary of the sea,an enduring barrier that it cannot cross?The waves surge, but they cannot prevail.They roar but cannot pass over it.

I made their widows more numerousthan the sand of the seas.I brought a destroyer at noonagainst the mother of young men.I suddenly released on heragitation and terrors.

The hosts of heaven cannot be counted; the sand of the sea cannot be measured. So, too, I will make the descendants of My servant David and the Levites who minister to Me innumerable.”
