'Slow' in the Bible

He said to them, "Foolish men, and slow of heart to believe in all that the prophets have spoken!

So, then, my beloved brothers, let every man be swift to hear, slow to speak, and slow to anger;

The Lord is not slow concerning his promise, as some count slowness; but is patient with us, not wishing that any should perish, but that all should come to repentance.
