וְכָל־עֲבָדָיו֙ עֹבְרִ֣ים עַל־יָד֔וֹ וְכָל־הַכְּרֵתִ֖י וְכָל־הַפְּלֵתִ֑י וְכָֽל־הַגִּתִּ֞ים שֵׁשׁ־מֵא֣וֹת אִ֗ישׁ אֲשֶׁר־בָּ֤אוּ בְרַגְלוֹ֙ מִגַּ֔ת עֹבְרִ֖ים עַל־פְּנֵ֥י הַמֶּֽלֶךְ׃
And all his servants passed on beside him; and all the Cherethites, and all the Pelethites, and all the Gittites, six hundred men that came after him from Gath, passed on before the king.
Rashi
over the Cherethites and the Pelethites The meaning is that they were nations, as it is written, (Zeph. 2:5): “Woe to... the nation of Cherethites,” and from their nations were mighty warriors with David, and Benaiah was over them. Another instance of this (II Sam. 15:18): “... and all his servants passed beside him, and all the Cherethites and all the Pelethites and all the Gittites.”
Radak
ותעבור המנחה על פניו, the words על פניו are equivalent to לפניו, “ahead of him, past him.” We encounter this expression in Samuel II 15,18 עוברים על פני המלך, “marching past the king.” According to Bereshit Rabbah 76,8 the words על פניו mean “under pressure.” In other words, the entire stratagem reflected Yaakov’s dire straits at the time.
