Isaiah 27:11

27:11 When its branches get brittle, they break;

women come and use them for kindling.

For these people lack understanding,

therefore the one who made them has no compassion on them;

the one who formed them has no mercy on them.

Luke 6:38

6:38 Give, and it will be given to you: A good measure, pressed down, shaken together, running over, will be poured into your lap. For the measure you use will be the measure you receive.”

James 2:13

2:13 For judgment is merciless for the one who has shown no mercy. But mercy triumphs over judgment.
