'Works' in the Bible

What is the profit, my brethren, if faith, any one may speak of having, and works he may not have? is that faith able to save him?

so also the faith, if it may not have works, is dead by itself.

But say may some one, Thou hast faith, and I have works, shew me thy faith out of thy works, and I will shew thee out of my works my faith:

And dost thou wish to know, O vain man, that the faith apart from the works is dead?

Abraham our father -- was not he declared righteous out of works, having brought up Isaac his son upon the altar?

dost thou see that the faith was working with his works, and out of the works the faith was perfected?

Ye see, then, that out of works is man declared righteous, and not out of faith only;

and in like manner also Rahab the harlot -- was she not out of works declared righteous, having received the messengers, and by another way having sent forth?

for as the body apart from the spirit is dead, so also the faith apart from the works is dead.

Who is wise and intelligent among you? let him shew out of the good behaviour his works in meekness of wisdom,
