Ecclesiastes 4:9-11

Young's Literal Translation

⁹ The two [are] better than the one, in that they have a good reward by their labour.

¹⁰ For if they fall, the one raiseth up his companion, but wo to the one who falleth and there is not a second to raise him up!

¹¹ Also, if two lie down, then they have heat, but how hath one heat?
