'Consider' in the Bible

Why do you see the speck of chaff that is in your brother's eye, but don't consider the beam that is in your own eye?

Consider the ravens: they don't sow, they don't reap, they have no warehouse or barn, and God feeds them. How much more valuable are you than birds!

Consider the lilies, how they grow. They don't toil, neither do they spin; yet I tell you, even Solomon in all his glory was not arrayed like one of these.

Or what king, as he goes to encounter another king in war, will not sit down first and consider whether he is able with ten thousand to meet him who comes against him with twenty thousand?
