It's an unverified quote which Netanyahu denied saying. In any case, Israel never funded Hamas as many claim; they allowed aid from Qatar which is pretty different.
I'll add that Israel allowed aid from Qatar after pressure from west and headlines in mass media that hundreds of thousands are going to starve in gaza if israel won't allow money from qatar.
the underlaying issues was that after PA tried to depose Hamas in Gaza and failed, it stopped paying salaries to everybody so Gaza was broke
