'Bitterly' in the Bible

But if you will not hear it, my soul shall weep in secret for [your] pride; and my eye shall weep bitterly, and run down with tears, because Yahweh's flock is taken captive.

Don't weep for the dead, neither bemoan him; but weep bitterly for him who goes away; for he shall return no more, nor see his native country.
