'Baptised' in the Bible

Then said he to the multitudes coming forth to be baptised by him, 'Brood of vipers! who did prompt you to flee from the coming wrath?

And there came also tax-gatherers to be baptised, and they said unto him, 'Teacher, what shall we do?'

And it came to pass, in all the people being baptised, Jesus also being baptised, and praying, the heaven was opened,

(And all the people who heard it, and the tax-gatherers, justified God, having been baptised with the baptism of John;

but the Pharisees and the lawyers rendered null as to themselves the counsel of God, not having been baptised by him.)

But I have a baptism to be baptised with, and how am I straitened until it shall have been accomplished!
