'Slow' in the Bible

So he said to them, "You foolish people -- how slow of heart to believe all that the prophets have spoken!

Understand this, my dear brothers and sisters! Let every person be quick to listen, slow to speak, slow to anger.

The Lord is not slow concerning his promise, as some regard slowness, but is being patient toward you, because he does not wish for any to perish but for all to come to repentance.
