Quotation sobre II Reyes 4:27

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”.
