a Breach of Trust
This is not the kind of sin that is a mistake. It is treason. It is unfaithfulness to our King. The kind of treachery where the wrongdoing is one of deception where one puts on a show of faithfulness.
“If any one commits a breach of faith and sins unwittingly in any of the holy things of the LORD, he shall bring, as his guilt offering to the LORD, a ram without blemish out of the flock, valued by you in shekels of silver, according to the shekel of the sanctuary; it is a guilt offering. Lev. 5:15
“If any one sins and commits a breach of faith against the LORD by deceiving his neighbor in a matter of deposit or security, or through robbery, or if he has oppressed his neighbor Lev. 6:2
Achan’s sin was that of a breach of trust [Josh 7:1, 22:20]. His sin was not just that he coveted and took things but that they were devoted things. Things that belonged not to another person but to another god. He had to have gone into a temple or shrine to acquire such things. This sin not only lead to Achan and his family being executed. Thirty six men, who did not even know of his sin, died in the failed attack on Ai.
How many of us are dying spiritually because we do not know of the Breach of Trust around us?
Blessed is the man who makes the LORD his trust, who does not turn to the proud, to those who go astray after false gods! Psa. 40:4
