'Strivings' in the Bible

Thou also hast delivered me from the strivings of my people, thou hast kept me to be head of the heathen: a people which I knew not shall serve me.

Thou hast delivered me from the strivings of the people; and thou hast made me the head of the heathen: a people whom I have not known shall serve me.

But avoid foolish questions, and genealogies, and contentions, and strivings about the law; for they are unprofitable and vain.
