'Stand in' in the Bible

Only live as citizens worthy of the good news of Christ: that whether coming and seeing you, whether being absent, I shall bear the things concerning you, that ye stand in one spirit, one soul, fighting together in faith of the good news;

I trust in the Lord Jesus for to send Timothy shortly unto you, that I also may be of good comfort, when I know what case ye stand in.

So then, my brothers and sisters, dear friends whom I long to see, my joy and crown, stand in the Lord in this way, my dear friends!
