And David sware moreover - Rather, "yet again." He met Jonathan's denial by repeating his statement and confirming it with an oath.

There is but a step between me and death - My life is in the most imminent danger. Your father has, most assuredly, determined to destroy me.

The same figure used here, there is but a step between me and death, may be found in Juvenal, who, satirizing those who risk their lives for the sake of gain in perilous voyages, speaks thus: -

I nune et ventis animam committe, dolato

Confisus ligno, digitis a morte remotus

Quatuor aut septem, si sit latissima teda.

Sat. xii., ver. 57.

"Go now, and commit thy life to the winds,

trusting to a hewn plank, four or seven fingers thick,

if the beam out of which it has been cut have been large enough."

And David sware moreover, and said,.... To assure Jonathan of the truth of it, that he did most certainly seek after his life, of which, as he had no doubt himself, by an oath he endeavoured to remove any that might be in Jonathan, who was not willing to believe his father could be guilty of so foul a crime:

thy father certainly knoweth that I have found grace in thine eyes: that he was high in his favour, that he had a great value for him, and he had a large share in his love and friendship, and that was the reason why he hid from him his base intentions:

and he saith, let not Jonathan know this, lest he be grieved; as he would be, both for the evil his father would be guilty of, and the danger David, his beloved friend, would be in:

but truly, as the Lord liveth, and as thy soul liveth, there is but a step between me and death; as appeared by his casting a javelin at him, 1 Samuel 18:11, sending messengers to his own house to slay him, 1 Samuel 19:11, and others to Naioth to seize him, 1 Samuel 19:20, and coming himself thither with an intention to kill him, 1 Samuel 19:22, and in each of these instances he had a narrow escape for his life; and this he declared in the most solemn manner by an oath, for the confirmation of the truth of it to Jonathan.

But David had looked deeper into Saul's heart. He replied with an oath ("he sware again," i.e., a second time), "Thy father knoweth that I have found favour in thine eyes (i.e., that thou art attached to me); and thinketh Jonathan shall not know this, lest he be grieved. But truly, as surely as Jehovah liveth, and thy soul liveth, there is hardly a step (lit. about a step) between me and death." כּי introduces the substance of the oath, as in 1 Samuel 14:44, etc.

And David sware moreover, and said, Thy father certainly knoweth that I have found grace in thine eyes; and he saith, Let not Jonathan know this, lest he be grieved: but truly as the LORD liveth, and as thy soul liveth, there is but a {b} step between me and death.

(b) I am in great danger of death.

20:3 David sware - The matter being of great moment, and Jonathan doubting the truth of it, he confirms his word with an oath, which follows in the end of the verse . Only he interposeth a reason why Saul concealed it from Jonathan.

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.
