Who shall tell me? - Who shall give me the necessary information? What means wilt thou use to convey this intelligence to me?

Then said David to Jonathan, who shall tell me?.... The disposition of Saul's mind towards him, whether he gave a kind answer to the report of Jonathan concerning him:

or what if thy father answer thee roughly? or hard words, as the Targum, whether he answers in a kind, loving, and smooth manner, or whether in a rough and angry one: the question is here, how he should be informed of this, since especially, if in the latter, it would not be safe for Jonathan to come himself to him, nor could he well trust the message with any other. Abarbinel thinks, that the first of these expressions is by way of question, who should declare to him his father's will and intention, whether good or bad: and the latter by way of outcry, woe unto me, if thy father should answer thee roughly; I greatly fear he will chide thee for my sake; my heart will be filled with sorrow if thou shouldest suffer reproach and rebuke on my account.

To this friendly assurance David replied, "Who will tell me?" sc., how thy father expresses himself concerning me; "or what will thy father answer thee roughly?" sc., if thou shouldst attempt to do it thyself. This is the correct explanation given by De Wette and Maurer. Gesenius and Thenius, on the contrary, take או in the sense of "if perchance." But this is evidently incorrect; for even though there are certain passages in which או may be so rendered, it is only where some other case is supposed, and therefore the meaning or still lies at the foundation. These questions of David were suggested by a correct estimate of the circumstances, namely, that Saul's suspicions would leave him to the conclusion that there was some understanding between Jonathan and David, and that he would take steps in consequence to prevent Jonathan from making David acquainted with the result of his conversation with Saul.

Then said David to Jonathan, Who {f} shall tell me? or what if thy father answer thee roughly?

(f) If your father favours me.

20:1-10 The trials David met with, prepared him for future advancement. Thus the Lord deals with those whom he prepares unto glory. He does not put them into immediate possession of the kingdom, but leads them to it through much tribulation, which he makes the means of fitting them for it. Let them not murmur at his gracious appointment, nor distrust his care; but let them look forward with joyful expectation to the crown which is laid up for them. Sometimes it appears to us that there is but a step between us and death; at all times it may be so, and we should prepare for the event. But though dangers appear most threatening, we cannot die till the purpose of God concerning us is accomplished; nor till we have served our generation according to his will, if we are believers. Jonathan generously offers David his services. This is true friendship. Thus Christ testifies his love to us, Ask, and it shall be done for you; and we must testify our love to him, by keeping his commandments.
