'Keep' in the Bible

in my prayers; always pleading that somehow, by God’s will, I may now at last come to you.

Circumcision [the sign of the covenant of Abraham] is indeed of value if you practice the Law; but if you habitually break the Law, your circumcision has become uncircumcision [it is meaningless in God’s sight].

Then he who is physically uncircumcised but keeps [the spirit of] the Law will judge you who, even though you have the written code and circumcision, break the Law.

being fully convinced that God had the power to do what He had promised.

Owe nothing to anyone except to love and seek the best for one another; for he who [unselfishly] loves his neighbor has fulfilled the [essence of the] law [relating to one’s fellowman].
