# is even more than
This idiom means that something is more important than something else. In this case, these two commandments are more pleasing to God that burnt offering and sacrifices. This may be written clearly. AT: "is even more important than" or "is even more pleasing to God than" (See: [[rc://en/ta/man/translate/figs-idiom]])
# You are not far from the kingdom of God

AT: "You are close to submitting to God as king" (See: [[rc://en/ta/man/translate/figs-litotes]] and [[rc://en/ta/man/translate/figs-metaphor]])
