'Worlds' in the Bible

but we speak God's wisdom in a mystery, even the wisdom that hath been hidden, which God foreordained before the worlds unto our glory:

Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds;

Through faith we understand that the worlds were framed by the word of God, so that things which are seen were not made of things which do appear.
