Then said Jonathan unto David,.... Now giving credit to what he had said, and in order to comfort and support him under the apprehensions he had of danger:

whatsoever thy soul desireth, I will even do it for thee; for the preservation of his life, by speaking to his father on his behalf, endeavouring to dissuade him from his evil intentions, or by hiding and concealing him in some obscure place, that he might not execute his evil designs upon him, or by any method he could point out to him.

When Jonathan answered, "What thy soul saith, will I do to thee," i.e., fulfil every wish, David made this request, "Behold, to-morrow is new moon, and I ought to sit and eat with the king: let me go, that I may conceal myself in the field (i.e., in the open air) till the third evening." This request implies that Saul gave a feast at the new moon, and therefore that the new moon was not merely a religious festival, according to the law in Numbers 10:10; Numbers 28:11-15, but that it was kept as a civil festival also, and in the latter character for two days; as we may infer both from the fact that David reckoned to the third evening, i.e., the evening of the third day from the day then present, and therefore proposed to hide himself on the new moon's day and the day following, and also still more clearly from 1 Samuel 20:12, 1 Samuel 20:27, and 1 Samuel 20:34, where Saul is said to have expected David at table on the day after the new moon. We cannot, indeed, conclude from this that there was a religious festival of two days' duration; nor does it follow, that because Saul supposed that David might have absented himself on the first day on account of Levitical uncleanness (1 Samuel 20:26), therefore the royal feast was a sacrificial meal. It was evidently contrary to social propriety to take part in a public feast in a state of Levitical uncleanness, even though it is not expressly forbidden in the law.

Then said Jonathan unto David, Whatsoever thy soul desireth, I will even do it for thee.

Whatsoever...: or, Say what is thy mind and I will do, etc

desireth: Heb. speaketh, or, thinketh

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.
