Judge Not Lest Ye Be Judged

I read this Bible passage with my daughter the other night: 

“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?"

Matthew 7:3

Which reminded me of a poem I read a long time ago in school. I tried retelling it from memory and, suffice it to say, she was not impressed. Ah, youth is wasted on the young. 

A portion from Robert Burns' 1786 poem To a Louse, On Seeing One on a Lady's Bonnet, at Church:

O would some Power the gift to give us

To see ourselves as others see us!

It would from many a blunder free us,

And foolish notion:

What airs in dress and gait would leave us,

And even devotion!
