Midrash sobre II Samuel 15:9

R. Chanina said: "The departure of the soul from the body is (Fol. 19) like a knotted rope passing through a loop-hole in the mast." R. Jochanan said: "Like ropes pulled through loop-holes in the board of a ship." (Fol. 29) R. Levi b. Chitha said: "He who takes leave of a dead body after burial shall not say, 'Go with peace,' but 'Go in peace.' However, if one takes leave of his living friend he should not say, 'Go in peace,' but 'Go with peace'; i.e., when one takes leave of a dead body he shall not say: 'Go with peace,' but 'Go in peace,' as it is said (Gen. 15, 15) But thou shalt come to thy fathers in peace (Beshalom); but when one takes leave of his living friend he should not say, 'Go in peace,' but 'Go with peace'; for Jethro, who said to Moses (Ex. 4, 18) Go with peace (Leshalom), Moses went and was successful; while David who said to Abshalam (II Sam. 15, 9) Go in peace, the latter went and hung himself." R. Levi said again: "He who goes out from the synagogue after prayer and enters the house of learning to study the Torah will be rewarded with permission to wait on the Divine Presence, for it is said (Ps. 84, 8) They go from strength to strength; each of them will appear before God in Zion."

And further said R. Abin the Levite: "He who leaves his friend [after escorting him a distance] must not say 'Go in peace' but Go with peace.' for Jethro said unto Moses (Ex. 4, 18.) Go with peace. He went and succeeded, but David said to Abshalom (II Sam. 15, 9.) Go in peace. He went and hanged himself." Further said R. Abin the Levite: "He who takes leave of the dead body [after burial] must not say 'Go with peace' but 'Go in peace,' for it is said (Gen. 15, 15.) But thou shalt come to thy fathers in peace." R. Levi b. Chiya said: "He who goes out from the synagogue [after prayer] and enters the house of learning and studies the Torah will be permitted to wait on the Divine Presence, for it is said (Ps. 84, 8.) They go from strength to strength; each of them will appear before God in Zion." R. Elazar in the name of R. Chanina said: "Scholars advance peace in the world, as it is said (Is. 54, 13.) And all thy children shall be taught by the Lord and great shall be the peace of thy children. Read not Banaich (Thy Children), but read it Bonaich (thy builders)"; Great peace have they who love thy Torah and there is no stumbling for them (Ps. 119, 115). Peace be within thy rampart, prosperity within thy palaces (Ib. 122, 7). For my brethren and associates' sake I would fain speak peace concerning Thee (Ib.). For the sake of the house of the Lord our God. I would seek thy good. The Lord will give strength unto his people; The Lord will bless his people with peace.
