וַיֹּ֣אמֶר אַבְנֵ֣ר אֶל־דָּוִ֡ד אָק֣וּמָה ׀ וְֽאֵלֵ֡כָה וְאֶקְבְּצָה֩ אֶל־אֲדֹנִ֨י הַמֶּ֜לֶךְ אֶת־כָּל־יִשְׂרָאֵ֗ל וְיִכְרְת֤וּ אִתְּךָ֙ בְּרִ֔ית וּמָ֣לַכְתָּ֔ בְּכֹ֥ל אֲשֶׁר־תְּאַוֶּ֖ה נַפְשֶׁ֑ךָ וַיְּשַׁלַּ֥ח דָּוִ֛ד אֶת־אַבְנֵ֖ר וַיֵּ֥לֶךְ בְּשָׁלֽוֹם׃
און אַבֿנר האָט געזאָגט צו דָוִדן: איך װעל אױפֿשטײן און װעל גײן, און איך װעל אײַנזאַמלען צו מײַן האַר דעם מלך גאַנץ ישׂראל, און זײ װעלן שליסן מיט דיר אַ בונד, און װעסט קיניגן װי װײַט דײַן האַרץ געלוסט. און דוד האָט אַװעקגעשיקט אַבֿנרן, און ער איז אַװעקגעגאַנגען בשלום.
Midrash Tanchuma Buber
(Exod. 4:18, cont.:) AND HE SAID TO HIM: PLEASE LET ME GO AND RETURN TO MY KINSFOLK <IN EGYPT AND SEE WHETHER THEY ARE STILL ALIVE. AND JETHRO SAID TO MOSES: > [GO FOR PEACE]. Everyone of whom it is written, FOR PEACE, goes and returns; but everyone of whom it is written, GO IN PEACE, goes and does not return.79Tanh., Exod. 1:21; Exod. R. 5:3; similarly Ber. 64a; MQ 29a. Concerning Abner it is written (in II Sam. 3:21): AND DAVID AWAY SENT ABNER, WHO WENT IN PEACE. He went and did not return, but Jethro said to Moses: GO FOR PEACE. He went and did return. Thus it is stated (in Exod. 4:18): AND JETHRO SAID TO MOSES: GO FOR PEACE.
Midrash Tanchuma
And Jethro said to Moses: “Go for peace” (Exod. 3:18). You find that everyone about whom it is written Go for peace departs and returns in peace, and that everyone concerning whom it is said Go in peace departs but does not return (in peace). Jethro said to Moses: Go for peace. And he departed and he returned in peace.
