O Lord God of Israel. — Now that the two friends have come to a remote solitary spot, Jonathan prefaces his reply to David’s piteous request by a very solemn invocation of that God they both loved so well. The vocative, however, “O Lord God,” &c., of the English Version has been generally looked upon as an impossible rendering — “there being no analogy for such a mode of address” — Lange.
The versions avoid it by supplying different words. So the Syriac and Arabic render “The Lord of Israel is my witness”; the LXX., “The Lord God of Israel knows.” Others have supplied a word which they find in two Hebrew MSS., “As the Lord God of Israel liveth.” The meaning, however, is perfectly clear.
Or the third day. — This statement of time on the part of Jonathan evidently assumes that the festival was continued the day after the “new moon” by a royal banquet. The time is thus reckoned: the present day; the morrow, which was the new moon festival; and the day after, which would reckon as the third day.
Behold, if there be good toward David. — In the event of the news being good — that is, if Saul, contrary to David’s expectation, spoke kindly of him — then Jonathan would send to him a special messenger; if, on the other hand, the king displayed enmity, in that case Jonathan would come himself and see David (for the last time). This sad message should be brought by no messenger.
