Matthew 7:6

7:6 Do not give what is holy to dogs or throw your pearls before pigs; otherwise they will trample them under their feet and turn around and tear you to pieces.

Matthew 9:17

9:17 And no one pours new wine into old wineskins; otherwise the skins burst and the wine is spilled out and the skins are destroyed. Instead they put new wine into new wineskins and both are preserved.”
