Job 13:26

For thou writest bitter things against me -Charges or accusations of severity. We use the word “bitter” now in a somewhat similar sense. We speak of bitter sorrow, bitter cold, etc. The language here is all taken from courts of justice, and Job is carrying cut the train of thought on which he had entered in regard to a trial before God. He says that the accusations which God had brought against him were of a bitter and severe character; charging him with aggravated offences, and recalling the sins of his youth, and holding him responsible for them.
