Misinterpretations often treat this as a standalone proverb equating all anger with inherent evil, ignoring the specific context of Saul's obsessive hostility toward David due to his fear of losing the throne. Others mistakenly attribute the words to Saul rather than Jonathan's strategic advice, or apply it literally today to probe relationships manipulatively without regard for the biblical narrative of covenant loyalty and divine sovereignty over kings.
I Samuel 20:7
King James Version (1769)
7 If he say thus, It is well; thy servant shall have peace: but if he be very wroth, then be sure that evil is determined by him.
This verse captures Jonathan's discerning plan to test King Saul's intentions toward David during a feast, where a calm response would assure David's safety, but intense anger would confirm Saul's malicious designs. It underscores themes of loyal friendship, wise observation of subtle cues in behavior, and the peril of unchecked jealousy in leadership, highlighting Jonathan's protective covenant with David amid rising court tensions.
