'Severest' in the Bible

and he writeth in the letter, saying, 'Place ye Uriah over-against the front of the severest battle, and ye have turned back from after him, and he hath been smitten, and hath died.'

for they still try to prevent our preaching to the Gentiles so that they may find salvation. They thus continually fill up the measure of their own sins, and God's anger in its severest form has overtaken them.
