How to use "pledge" in a sentence

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

With this pledge taken, I assume unhesitatingly the leadership of this great army of our people dedicated to a disciplined attack upon our common problems.

This much we pledge - and more.

To those old allies whose cultural and spiritual origins we share, we pledge the loyally of faithful friends

To those new states whom we welcome to the ranks of the free, we pledge our word that one form of colonial control shall not have passed away merely to be replaced by a far more iron tyranny

To those people in the huts and villages across the globe struggling to break the bonds of mass misery, we pledge our best efforts to help them, help themselves, for whatever period is required - not because the communists may be doing it, not because we seek their votes, but because it is right.

To our sister republics south of our border, we offer a special pledge - to convert our good words into good deeds - in a new alliance for progress - to assist free men and free governments in casting off the chains of poverty

To that world assembly of sovereign states, the United Nations, our last best hope in an age where the instruments of war have far outpaced the instruments of peace, we renew our pledge of support - to prevent it from becoming merely a forum for invective - to strengthen its shield of the new and the weak - and to enlarge the area in which its writ may run.

Finally, to those nations who would make them-selves our adversary, we offer not a pledge but a request: that both sides begin anew the quest for peace, before the dark powers of destruction unleashed by science engulf all humanity in planned or accidental self-destruction.
