# None of those things set apart for destruction must stick in your hand
"You must not keep any of the things God has commanded you to destroy". Yahweh cursing something and promising to destroy it is spoken of as if Yahweh were setting the object apart from other things.
# must stick in your hand
"must you keep"
# Yahweh will turn from the burning of his anger
"Yahweh will stop being angry"
# to your fathers
Here "fathers" means ancestors or forefathers.
