But there is something that I must say to my people, who stand on the warm threshold which leads into the palace of justice: In the process of gaining our rightful place, we must not be guilty of wrongful deeds. Let us not seek to satisfy our thirst for freedom by drinking from the cup of bitterness and hatred. We must forever conduct our struggle on the high plane of dignity and discipline. We must not allow our creative protest to degenerate into physical violence. Again and again, we must rise to the majestic heights of meeting physical force with soul force.

The marvelous new militancy which has engulfed the Negro community must not lead us to a distrust of all white people, for many of our white brothers, as evidenced by their presence here today, have come to realize that their destiny is tied up with our destiny. And they have come to realize that their freedom is inextricably bound to our freedom.

We cannot walk alone.

And as we walk, we must make the pledge that we shall always march ahead.

We cannot turn back.

参考译文
但是，对于站在通向正义之宫艰险门槛上的人们，有一些话我必须要说。在我们争取合法地位的过程中，切不要错误行事导致犯罪。我们切不要吞饮仇恨辛酸的苦酒，来解除对于自由的饮渴。我们应该永远得体地、纪律严明地进行斗争。我们不能容许我们富有创造性的抗议沦为暴力行动。我们应该不断升华到用灵魂力量对付肉体力量的崇高境界。
席卷黑人社会的新的奇迹般的战斗精神，不应导致我们对所有白人的不信任——因为许多白人兄弟已经认识到：他们的命运同我们的命运紧密相连，他们的自由同我们的自由休戚相关。他们今天来到这里参加集会就是明证。

我们不能单独行动。
当我们行动时，我们必须保证勇往直前。
我们不能后退。
