“Again, the kingdom of heaven is like a merchant in search of fine pearls, ⁴⁶ who, on finding one pearl of great value, went and sold all that he had and bought it."
(Matthew 13:45-46 -- ESV)

“See that you do not despise one of these little ones.  For I tell you that in heaven their angels always see the face of my Father who is in heaven. ¹² What do you think?  If a man has a hundred sheep, and one of them has gone astray, does he not leave the ninety-nine on the mountains and go in search of the one that went astray? ¹³ And if he finds it, truly, I say to you, he rejoices over it more than over the ninety-nine that never went astray. ¹⁴ So it is not the will of my Father who is in heaven that one of these little ones should perish."
(Matthew 18:11-14 -- ESV)
