'Partly' in the Bible

{And just as} you saw the feet and the toes, {partly potter's clay} and {partly iron}, it will be a divided kingdom; and {some hardness} of the iron will be [in it], {just as} you have seen the iron mixed with the wet clay.

And [as] the toes of the feet [were] partly iron and partly clay, [so] part of the kingdom will be strong {and partly brittle}.
