וַתְּהִ֤י עַל־יִפְתָּח֙ ר֣וּחַ יְהוָ֔ה וַיַּעֲבֹ֥ר אֶת־הַגִּלְעָ֖ד וְאֶת־מְנַשֶּׁ֑ה וַֽיַּעֲבֹר֙ אֶת־מִצְפֵּ֣ה גִלְעָ֔ד וּמִמִּצְפֵּ֣ה גִלְעָ֔ד עָבַ֖ר בְּנֵ֥י עַמּֽוֹן׃
Lalu roh Yang Mahakekal ada pada Yefta. Ia melintasi Gilead dan Manasye, lalu melintasi Mizpa di Gilead, dan dari Mizpa di Gilead ia bergerak maju menuju bani Amon.
Rashi
And a spirit enwrapped Amasai - Heb. רוּחַ, talent, a will or desire, not a spirit of prophecy; i.e., this desire and will enwrapped him so that he sprang first to speak before the sons of Benjamin and Judah who came with him. A similar instance is (Jud. 11:29): “And a spirit of the Lord was upon Jephthah” and he said: To you, David You say, “Have you come to me in peace?” We have surely come to you in peace. and with you, O son of Jesse We wish to be with you and at your assistance.
Rashi
והמצפה אשר אמר AND MIZPAH (literally, the Mizpah); BECAUSE HE SAID etc . — The word והמצפה and the Mizpah must refer to some well-known place bearing this name (for there are several places named Mizpah) it refers to the Mizpah which is in Mount Gilead — as it is written (Judges 11:29) “and he passed over Mizpah of Gilead”. Why was it also called Mizpah? Because each of them said to the other, “The Lord watch (יצף) between me and thee that thou shouldst not violate this covenant”.
