'Slow' in the Bible

And He said to them, “O foolish men and slow of heart to believe in all that the prophets have spoken!

This you know, my beloved brethren. But everyone must be quick to hear, slow to speak and slow to anger;

The Lord is not slow about His promise, as some count slowness, but is patient toward you, not wishing for any to perish but for all to come to repentance.
