God who works wonders combines the Hebrew word (‘oseh), which elsewhere means Maker, with the word pele’. That word speaks of things that are unusual and beyond the capacity of man; it is only used of God. So this name celebrates the miraculous works that only God can do.
God who works wonders in Hebrew:
ha’El ‘oseh pele’
