may Yahweh do to Jonathan and more also

This is an idiom. Jonathan uses this oath for emphasis and speaks of himself as if he were another person. Alternate translation: "may Yahweh do to me whatever harm my father intends to do to you, and even more than that" (See: rc://en/ta/man/translate/figs-idiom and rc://en/ta/man/translate/figs-pronouns)
