Krypto and its various forms are used in the Bible that was written in Greek (New Testament). This is a thought that makes translators work, hard. I am using the Mounce website as a reference. The simple transliteration is krypto, but it does take various forms and is used eighteen times. In the text we read it may be-hid/hide, hidden, secret, covered, or concealed. The Strong’s number is G 2928.  

Some of the verses that caught my attention are:

Matthew 13: 44 Again, the kingdom of heaven is like unto treasure hid in a field; the which when a man hath found, he hideth, and for joy thereof goeth and selleth all that he hath, and buyeth that field. (KJV)

Matthew 25:25 And I was afraid, and went and hid thy talent in the earth: lo, there thou hast that is thine. (KJV) This is from the Sermon on the Two Mounts.

On the lighter side, Superman’s dog is named Krypto. That should come from kryptonite and not something hidden.
