Preston Kavanagh, «The Jehoiachin Code in Scripture’s Priestly Benediction», Vol. 88 (2007) 234-244
Coding in the OT is plausible because of the Exile’s profusion of scripture, the Diaspora’s need for secure communication, and the ancient world’s widespread use of cryptography. A code exists in Num 6,24-26 that uses one letter per text word, from words spaced at regular intervals, with letters used in any sequence. Coding of Jehoiachin’s name in the MT’s Priestly Benediction establishes the mid-sixth century B.C.E. as the earliest possible time for the Ketef Hinnom amulets. Moreover, since the Ketef Hinnom scribe appears to have understood nothing of the benediction’s Jehoiachin coding, the amulets could be considerably later than mid-sixth century.

from regularly spaced text words, one letter per word. The interval can range
from one (letters taken from consecutive text words), to four (a letter from
every fourth text word). Suppose the author wished to conceal a four-letter
word while using an interval of two. He or she would have employed single
letters from text words one, three, five, and seven. Any letter within the
proper Hebrew word could be used. There seems to have been just one other
general rule: the concealed word could have letters falling in any sequence.
Thus cat could also be spelled cta, act, atc, tca, and tac.
In summary, to form coded words a biblical author could:
– Use one letter per text word
– Employ text words spaced at regular intervals
– Arrange letters in any sequence.
Under the rules outlined above, the benediction’s fifteen Hebrew words
conceal fourteen spellings of Jehoiachin, ˆykywy. The Bible has only one
Jehoiachin, and it clearly establishes his dates. Jehoiachin briefly reigned over
Judah before his exile in March of 597 B.C.E. (2 Kgs 24,12). Thirty-seven
years later, in late March (Jer 51,31) or early April (2 Kgs 25,27) of 561, the
Judean king emerged from a Babylonian prison. One could add a few post-
prison years to establish the span during which Jehoiachin might have
influenced scripture. That period between 597 and, say, 558 B.C.E. sets the
probable limit for the Priestly Benediction’s composition, which would have
been created during or immediately after Jehoiachin’s lifetime. However,
since the Priestly Benediction is a benediction, it is far more likely to have
been written immediately after Jehoiachin’s death — unless the coded
Jehoiachin spellings are coincidental. This table shows how the author by
accident or intent worked those fourteen coded spellings into the benediction.

The Letter Sequence column shows the scrambled order of the Hebrew
spellings. They are like anagrams, except that letters are drawn from more
than one text word. Notice that only item 2 gives the true letter sequence for
this version of Jehoiachin, which is ˆykywy. The Word Interval column
