'Contend' in the Bible

Now some Sadducees (who contend that there is no resurrection) came to him.

Now I exhort you, brothers, through our Lord Jesus Christ and through the love of the Spirit, to contend along with me in your prayers on my behalf to God,

And if also any one contend in the games, he is not crowned unless he contend lawfully.

And a bondman of the Lord ought not to contend, but be gentle towards all; apt to teach; forbearing;

Beloved, when I gave all diligence to write unto you of the common salvation, it was needful for me to write unto you, and exhort you that ye should earnestly contend for the faith which was once delivered unto the saints.
