'Stepped' in the Bible

Therefore He said He would destroy them,[And He would have done so] had not Moses, His chosen one, stepped into the gap before Him,To turn away His wrath from destroying them.

“Then they will go forth and lookUpon the dead bodies of the [rebellious] menWho have transgressed against Me;For their worm (maggot) will not die,And their fire will not go out;And they will be an abhorrence to all mankind.”
