'Establish' in the Bible

For they [the gifts, sacrifices, and ceremonies] deal only with [clean and unclean] food and drink and various ritual washings, [mere] external regulations for the body imposed [to help the worshipers] until the time of reformation [that is, the time of the new order when Christ will establish the reality of what these things foreshadow—a better covenant].

then He said, “Behold, I have come to do Your will.” [And so] He does away with the first [covenant as a means of atoning for sin based on animal sacrifices] so that He may inaugurate and establish the second [covenant by means of obedience].
