He never specifically mentioned a lot of things: child abuse, rape, necrophilia, bestiality, etc...
Actually did mention beastiality:
Ex 22:19 Whosoever lieth with a beast shall surely be put to death.
Leviticus 18:23
Neither shalt thou lie with any beast to defile thyself therewith: neither shall any woman stand before a beast to lie down thereto: it is confusion.
Leviticus 20:15
And if a man lie with a beast, he shall surely be put to death: and ye shall slay the beast.
Deuteronomy 27:21
Cursed be he that lieth with any manner of beast. And all the people shall say, Amen
RAPE:
25But if a man find a betrothed damsel in the field, and the man force her, and lie with her: then the man only that lay with her shall die.
26But unto the damsel thou shalt do nothing; there is in the damsel no sin worthy of death: for as when a man riseth against his neighbour, and slayeth him, even so is this matter:
27For he found her in the field, and the betrothed damsel cried, and there was none to save her.
Jesus. I believe the charge was that Jesus never specifically mentioned those things.
