'Avail' in the Bible

Yet all this is of no avail to me so long as I see Mordecai the Jew sitting at the king's gate.

Because there is wrath, beware lest it take thee away through chastisement: then a great ransom could not avail thee.

Thou wast wearied by the multitude of thy ways; but thou saidst not, It is of no avail. Thou didst find a quickening of thy strength; therefore thou wast not sick of it.
