'Substance' in the Bible

The wicked [those who live in disobedience to God’s law] are not so,But they are like the chaff [worthless and without substance] which the wind blows away.

He made Joseph lord of his houseAnd ruler of all his possessions,

He also struck down all the firstborn in their land,The first fruits and chief substance of all their strength.

Your eyes have seen my unformed substance;And in Your book were all writtenThe days that were appointed for me,When as yet there was not one of them [even taking shape].
