Matthew 18:10-11, 14

“Do not despise the least* from the people among you.  And I’ll tell you why. In heaven, their angels channel all they see into the presence of my Father, who is in heaven, because the Son of man came to save those who are perishing.”

“It is not the will of your Father, who is in heaven, that even one of the least of you should perish.”

The least.

The Greek word used here is mikros which means in this context “those who are the smallest in size, fewest in number, youngest or those lacking in dignity or capability among you.” The English word micro comes from this Greek word.
