Psalm 75:8 (a) This is a picture of the bitterness of the wrath of GOD in its worst form and character. The teaching that a "loving GOD will not punish sinners" is repudiated by this statement. The wicked will suffer the punishment of GOD to the last drop.
Isaiah 51:17, Isaiah 51:22 (a) In this place the fury and the wrath of GOD have been poured out on Jerusalem to the last drop. GOD punished Israel in great wrath because they turned against Him in such a wicked and evil way.
