17 Ngokholo u-Abrahama wathi elingwa,+ kwaba angathi usenikele ngo-Isaka. (Indoda le eyayizamukele ithokoza izithembiso yazama ukunikela ngendodana yayo ezelwe yodwa.)+ 18 U-Abrahama wenza njalo lanxa wayetshelwe ukuthi: “Okuzathiwa yinzalo yakho kuzavela ku-Isaka.”+ 19 Kodwa yena wazitshela ukuthi uNkulunkulu uyenelisa ukuyivusa indodana yakhe lanxa ingafa, waseyamukela ivela kwabafileyo ngendlela engumfanekiso.+

21 Ubaba wethu u-Abrahama akuzange yini kuthiwe ulungile ngemisebenzi ngemva kokunikela ngendodana yakhe u-Isaka e-alithareni?+
