'Twin' in the Bible

Sure enough, when her due date arrived, she delivered twin sons.

Your teeth are like a flock of newly shorn sheepcoming up from washing,each one having a twin,and not one missing.

Your teeth are like a flock of ewescoming up from washing,each one having a twin,and not one missing.

"These twin things have come upon you (who can feel sorry for you?): ruin and destruction, famine and the sword who can console you?
