'Adequate' in the Bible

Now who indeed has adequate strength to build a house for him? For the heavens and {the highest heavens} are not able to contain him. Now who [am] I that I would build a house for him, except to burn incense before him?

So they said, "Lord, behold, here [are] two swords!" And he said to them, "It is adequate."

Not that we are adequate in ourselves to consider anything as from ourselves, but our adequacy [is] from God,

who also makes us adequate [as] servants of a new covenant, not of the letter, but of the Spirit, for the letter kills, but the Spirit gives life.
