'Slow' in the Bible

Won't God grant his chosen people justice when they cry out to him day and night? Is he slow to help them?

Then Jesus told them, "O, how foolish you are! How slow you are to believe everything the prophets said!

You must understand this, my dear brothers. Everyone should be quick to listen, slow to speak, and slow to get angry.

The Lord is not slow about his promise, as some people understand slowness, but is being patient with you. He does not want anyone to perish, but wants everyone to repent.
