And as touching the matter which thou and I have spoken of,.... The covenant they had made between them and their families:
behold, the Lord be between me and thee for ever: as a witness of the covenant, and a revenger of those that should break it; so the Targum,"behold, the Word of the Lord be between me and thee a witness for ever.''

as touching the matter which thou and I have spoken of--The plan being concerted, the friends separated for a time, and the amiable character of Jonathan again peers out in his parting allusion to their covenant of friendship.

This arrangement was to remain an eternal secret between them. "And (as for) the word that we have spoken, I and thou, behold, the Lord is between me and thee for ever," namely, a witness and judge in case one of us two should break the covenant (vid., Genesis 31:48-49). This is implied in the words, without there being any necessity to assume that עד had dropped out of the text. "The word" refers not merely to the sign agreed upon, but to the whole matter, including the renewal of the bond of friendship.

Between - As a witness and a judge between us and our families for ever, if on either side this league of friendship be violated.
