Hebrews 10:24-25 (ESV)
24 And let us consider how to stir up one another to love and good works,
25 not neglecting to meet together, as is the habit of some, but encouraging one another, and all the more as you see the Day drawing near.
Proverbs 18:24 (NIV)
A man of many companions may come to ruin, but there is a friend who sticks closer than a brother.
