Job 23:2

Bitter. Literally, “rebellious.” “Bitter” is the reading of the Syriac, the Vulgate, and the Targums. Job does not apologize for his complaints. He acknowledges that, notwithstanding all his opponents have said about his right to complain, he still complains as bitterly as ever.

Stroke. Literally, “hand.” The expression may be translated “my hand is [lies] heavy upon my groaning,” meaning that Job tries to repress his groaning, which in no adequate measure reflects his calamities. The LXX renders the sentence, “His hand has been made heavy upon my groaning.”
