15 See to it that no one fails to obtain the grace of God; that no root of bitterness springs up and causes trouble, and through it many become defiled.
15 watching lest [there be] any one who lacks the grace of God; lest any root of bitterness springing up trouble [you], and many be defiled by it;
15 Make sure no one gets left out of God's generosity. Keep a sharp eye out for weeds of bitter discontent. A thistle or two gone to seed can ruin a whole garden in no time.
