'Availeth' in the Bible

Yet all this availeth me nothing, so long as I see Mordecai the Jew sitting at the king's gate.

Indeed, no prayer availeth when he stretcheth out his hand: though they cry when he destroyeth.

I said of laughter, Madness! and of mirth, What availeth it?

For in Jesus Christ neither circumcision availeth any thing, nor uncircumcision; but faith which worketh by love.

For in Christ Jesus neither circumcision availeth any thing, nor uncircumcision, but a new creature.

Confess your faults one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much.
