1 Samuel 20:42  (King James Version)
And Jonathan said to David, Go in peace, forasmuch as we have sworn both of us in the name of the LORD, saying, The LORD be between me and thee, and between my seed and thy seed for ever. And he arose and departed: and Jonathan went into the city.

Go in peace
22 ; 1:17 Numbers 6:26 ; Luke 7:50 ; Acts 16:36

forasmuch as
or, the Lord be witness of that which, etc.

And he arose
The separation of two such faithful friends was equally grievous to them both, but David's case was the more deplorable: for when Jonathan was returning to his family and friends, David was leaving all his comforts, even those of God's sanctuary, and therefore his grief exceeded Jonathan's; or, perhaps it was because his temper was more tender and his passions stronger. They referred each other to the covenant of friendship that was between them, both of them being comforted thereby in this very mournful separation:--"We have sworn both of us in the name of the Lord, for ourselves and our heirs, that we and they will be faithful and kind to each other from generation to generation."
