'Wet' 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 [in] that you saw the iron was mixed with wet clay, [so] {they will mix in marriage} and they will not cling {to one another}, just as iron [does] not mix with clay.
