A dictionary is needed, please.

"And why worry about a speck in your friend's eye when you have a log in your own?"

I need a dictionary in which I can find the figurative meanings for speck and log. Will you help me, please? Also, I receive Daily Devotion that need to be dealt with correctly when it comes to word meaning.

Thank you,

It's Matthew 7:3 from the Bible. A "speck" is a little piece. In this case a little piece of wood, like sawdust. The "log" would be an entire large piece of a tree.

The point is that one should not worry about the small problems or faults that others have, since you have much larger faults of your own.

Have some variations of the wording:
Matthew 7:3 "Why do you look at the speck of sawdust in your brother's eye and pay no attention to the plank in your own eye?

There are several other versions here, including those with motes and beams.
