At dumating siya sa tao ng Diyos sa bundok, at kumapit siya sa kanyang mga paa. At lumapit si Gehazi upang itulak siya palayo; ngunit sinabi ng tao ng Diyos: “Pabayaan mo siya, sapagkat mapait ang kalooban niya; at inilihim ito sa akin ng Walang-Hanggan, at hindi Niya sinabi sa akin.”
Ibn Ezra
2. And the remaining camp can remain - perhaps it will be the case that they will run away. Or that his brother's anger will abate with his attack on the first camp, or reprieve and rescue will come from God and similarly “If the Arameans prove too strong for me, you come to my aid" (II Samuel 10:11).
Rashi
לא ירפך means, He will not let loose of thee so as not to hold thee fast by His hands. The expression לא ירפך is an expression signifying: He will not cause something (our Hiphil) — He will not give thee any looseness, i.e. He will not separate you from Him. Similar is (Song 3:4) “I hold him fast, and I will not let him loose (אַרְפֶּנוּ )”, which is not vowelled אֶרְפֶּנוּ (which is Kal and an impossible form of the root רפה “to be loose”). Always the expression “letting slack (רפה)” in the Hiphil refers to one who causes looseness to others or to one who causes it to himself. For example (2 Kings 4:2) הרפה לה means, “give her looseness”; (Deuteronomy 9:14) הרף ממני means, “Give looseness to thyself from off me”.
