'Competent' in the Bible

not that we are competent of ourselves to think anything as of ourselves, but our competency is of God;

who has also made us competent, as ministers of the new covenant; not of letter, but of spirit. For the letter kills, but the Spirit quickens.

And the things thou hast heard of me in the presence of many witnesses, these entrust to faithful men, such as shall be competent to instruct others also.
