Numbers 10:31

And Moses said, "Oh nay, leave us not, for thou knowest where is best for us to pitch in the wilderness: and thou shalt be our eyes.

I was an eye unto the blind, and a foot to the lame;

I will inform thee, and teach thee in the way wherein thou shalt go; and I will guide thee with mine eye.

For the body is not one member, but many.

Bear ye one another's burden; and so fulfill the law of Christ.

And he said, Leave us not, I pray thee; forasmuch as thou knowest how we are to encamp in the wilderness, and thou mayest be to us instead of eyes.

I was an eye unto the blind, and a foot to the lame;

I will inform thee, and teach thee in the way wherein thou shalt go; and I will guide thee with mine eye.

For the body is not one member, but many.

Bear ye one another's burden; and so fulfill the law of Christ.

And the eye cannot say unto the hand, "I have no need of thee," nor the head also to the feet, "I have no need of you."
