Remember ye not the former things, neither consider the things of old. Behold, I will do a new thing; now it shall spring forth; shall ye not know it? I will even make a way in the wilderness, and rivers in the desert. Isaiah 43:18-19
No man putteth a piece of new cloth unto an old garment, for that which is put in to fill it up taketh from the garment, and the rent is made worse. Neither do men put new wine into old bottles: else the bottles break, and the wine runneth out, and the bottles perish: but they put new wine into new bottles, and both are preserved. Matthew 9:16-17
Again, the kingdom of heaven is like unto a net, that was cast into the sea, and gathered of every kind: Which, when it was full, they drew to shore, and sat down, and gathered the good into vessels, but cast the bad away. … every [person] … is like unto a man that is an householder, which bringeth forth out of his treasure things new and old. Matthew 13:48-52
Purge out therefore the old leaven, that ye may be a new lump. … neither with the leaven of malice and wickedness; but with the unleavened bread of sincerity and truth. 1 Corinthians 5:7-8
