1 Samuel 20:12

And Jonathan said unto David, O Lord God of Israel ,.... Or by the Lord God of Israel, I swear unto thee; for this is the form of the oath, as Jarchi and Kimchi observe:

when I have sounded my father about tomorrow any time, or the third day ; searched, inquired, and found out how his disposition is:

and, behold, if there be good toward David ; if he is well disposed to him, as may appear by speaking respectfully of him, or kindly inquiring after him, and by being satisfied with the account given him:

and I then send not unto thee, and show it thee ; then let the vengeance of God fall upon me in some remarkable manner or another, as follows; or "shall I not then send unto thee, and show it thee" F20 ולא אז אשלח אליך "an non tune mitterem?" Junius & Tremellius; "nonne tunc mittam ad te?" so some in Vatablus. ? certainly I will; that is, I will send a messenger to thee to acquaint thee with it, who shall tell it, and cause thee to hear it, as from myself.
