From Mrs. Gage's introduction in the History of Woman Suffrage:
Several ministers attended the second day of the Woman's Rights Convention, and were not shy in voicing their opinion of man's superiority over women. One claimed "superior intellect", one spoke of the "manhood of Christ," and still another referred to the "sin of our first mother." Suddenly, Sojourner Truth rose from her seat in the corner of the church. "For God's sake, Mrs.Gage, don't let her speak!" half a dozen women whispered loudly, fearing that their cause would be mixed up with Abolition. Sojourner walked to the podium and slowly took off her sunbonnet. Her six-foot frame towered over the audience. She began to speak in her deep, resonant voice:

Version One:
As narrated by Frances Gage in History of Woman Suffrage:

Version Two:
As reported in the Anti-Slavery Bugle, June 21, 1851:

"Wall, chilern, whar dar is so much racket dar must be somethin’ out o’ kilter. I tink dat ‘twixt de niggers of de Souf and de womin at de Norf, all talkin’ ‘bout rights, de white men will be in a fix pretty soon. But what’s all dis here talkin’ ‘bout?

"I want to say a few words about this matter. I am a woman’s rights.

"Dat man ober dar say dat womin needs to be helped into carriages, and lifted ober ditches, and to hab de best place everywhar. Nobody eber helps me into carriages, or ober mud-puddles, or gibs me any best place!" And raising herself to her full height, and her voice to a pitch like rolling thunder, she asked "And a’n’t I a woman? Look at me! Look at my arm!" (and she bared her right arm to the shoulder, showing her tremendous muscular power). "I have ploughed, and planted, and gathered into barns, and no man could head me! And a’n’t I a woman? I could work as much and eat as much as a man—when I could get it—and bear de lash as well! And a’n’t I a woman?

I have as much muscle as any man, and can do as much work as any man. I have plowed and reaped and husked and chopped and mowed, and can any man do more than that? I have heard much about the sexes being equal. I can carry as much as any man, and can eat as much too, if I can get it. I am as strong as any man that is now.

I have born thirteen chilern, and seen ‘em mos’ all sold off to slavery, and when I cried out with my mother’s grief, none but Jesus heard me! And a’n’t I a woman?

"Den dey talks ‘bout dis ting in de head; what dis dey call it?" ("Intellect," whispered someone near.) "Dat’s it, honey. What’s dat got to do wid womin’s rights or nigger’s rights? If my cup won’t hold but a pint, and yourn holds a quart, wouldn’t ye be mean not to let me have my little half-measure full?" And she pointed her significant finger, and sent a keen glance at the minister who had made the argument. The cheering was long and loud.

As for intellect, all I can say is, if woman have a pint, and man a quart—why can’t she have her little pint full? You need not be afraid to give us our rights for fear we will take too much,—for we can’t take more than our pint’ll hold.

The poor men seem to be all in confusion, and don’t know what to do. Why children, if you have woman’s rights, give it to her and you will feel better. You will have your own rights, and they won’t be so much trouble.

I can’t read, but I can hear. I have heard the bible and have learned that Eve caused man to sin. Well, if woman upset the world, do give her a chance to set it right side up again. The Lady has spoken about Jesus, how he never spurned woman from him, and she was right. When Lazarus died, Mary and Martha came to him with faith and love and besought him to raise their brother. And Jesus wept and Lazarus came forth.

"Den dat little man in black dar, he say women can’t have as much rights as men, ‘cause Christ wan’t a woman! Whar did your Christ come from?" Rolling like thunder couldn’t have stilled that crowd, as did those deep, wonderful tones, as she stood there with outstretched arms and eyes of fire. Raising her voice still louder, she repeated, "Whar did your Christ come from? From God and a woman! Man had nothin’ to do wid Him." Oh, what a rebuke that was to that little man.

And how came Jesus into the world? Through God who created him and a woman who bore him. Man, where is your part?

But the women are coming up blessed be God and a few of the men are coming up with them. But man is in a tight place, the poor slave is on him, woman is coming on him, he is surely between a hawk and a buzzard."

.Turning again to another objector, she took up the defense of Mother Eve. I can not follow her through it all. It was pointed, and witty, and solemn; eliciting at almost every sentence deafening applause; and she ended by asserting: "If de fust woman God ever made was strong enough to turn de world upside down all alone, dese women togedder" (and she glanced her eye over the platform) "ought to be able to turn it back, and get it right side up again! And now dey is asking to do it, de men better let’ em." Long-continued cheering greeted this. "Bleeged to ye for hearin’ on me, and now old Sojourner han’t got nothin’ more to say."
