NIV
For [the ceremonies] deal only with clean and unclean meats and drinks and different washings, [mere] external rules and regulations for the body imposed to tide the worshipers over until the time of setting things straight [of reformation, of the complete new order when Christ, the Messiah, shall establish the reality of what these things foreshadow--a better covenant].
AMP
Which stood only in meats and drinks, and divers washings, and carnal ordinances, imposed on them until the time of reformation.
