Deuteronomy 26:14 'I have not eaten of it while mourning, nor have I removed any of it while I was unclean, nor offered any of it to the dead. I have listened to the voice of the LORD my God; I have done according to all that You have commanded me.

Ezekiel 24:17 "Groan silently; make no mourning for the dead. Bind on your turban and put your shoes on your feet, and do not cover your mustache and do not eat the bread of men."

Hosea 9:4 They will not pour out drink offerings of wine to the LORD, Their sacrifices will not please Him. Their bread will be like mourners' bread; All who eat of it will be defiled, For their bread will be for themselves alone; It will not enter the house of the LORD. (NASB ©1995)
