Before the Ark of the Covenant could be successfully brought to Jerusalem  , there was a false start in which the people of Israel neglected to properly carry the Ark of Covenant with poles and instead adopted the old Philistine expedient of using ox-carts, leading to the death of Uzza, who had put his hand out and touched the Ark of the Covenant, being struck down by God. It is not the purpose of this entry to discuss this much-discussed incident and its connection of divine judgment with the breaking of even seemingly obscure laws of God.
However, at the end of this story there is a comment about a particularly notable Son of Korah who received a blessing from God while keeping the Ark of the Covenant safe, when David was afraid about divine judgment after God’s judgment of Uzza. We find Obed-Edom the Gittite, who happened to also be a member of the Sons of Korah , hosting the Ark of the Covenant for three months, and provoking David’s jealousy (perhaps) by the blessings he received from God for doing so in a respectful manner.
This part of the story is written in two passages of the Bible: 2 Samuel 6:9-12 and 1 Chronicles 13:12-14. Let us look at both of them and then provide some comment. 2 Samuel 6:9-12 reads: “David was afraid of the Lord that day; and he said, “How can the ark of the Lord come to me?” So David would not move the ark of the Lord with him into to the City of David; but David took it aside into the house of Obed-Edom the Gittite. The ark of the Lord remained in the house of Obed-Edom the Gittite three months. And the Lord blessed Obed-Edom and all his household. Now it was told King David, saying, “The Lord has blessed the house of Obed-Edom and all that belongs to him, because of the ark of God.” So David went and brought up the ark of God from the house of Obed-Edom to the City of David with gladness.” 1 Chronicles 13:12-14 reads similarly: “David was afraid of God that day, saying, “How can I bring the ark of God to me?” So David would not move the ark with him into the City of David, but took it aside into the house of Obed-Edom the Gittite. The ark of God remained with the family of Obed-Edom in his house three months. And the Lord blessed the house of Obed-Edom and all that he had.”
Here we see something rather curious. The superficial reader of these accounts would not be aware that Obed-Edom was an Israelite at all (since the adjective Gittite is normally associated with the city of Gath, though there was a city of Judah, Moreseth Gath, that was itself associated with servants of God like the minor prophet Micah). It is only with a knowledge of the genealogies of 1 Chronicles  that one understands that Obed-Edom was a gatekeeper of the Sons of Korah, and it makes perfect sense why a king concerned about taking the ark of the covenant into his city would turn aside to Obed Edom’s house, because he was a gatekeeper and his house would have presumably been close to the gate.
Let us also comment a little on the fact that God conspicuously blessed the presence of the Ark of the Covenant in the household of Obed-Edom. It took about three months for the blessings to become noticeable to King David, at which point he promptly had the Ark of the Covenant moved into the City of David so that God could bless him instead of his Levite gatekeeper. Nonetheless, it is remarkable to note that the blessing of God for this faithful Levite whose family must have treated the Ark of the Covenant with considerable respect serves as a counterpoint to the judgment on those who did not treat the ark with such respect. The function of the tale serves to remind us that God rewards obedience and punishes disobedience, sometimes in this world in ways that are obvious for others to see.
Obed-Edom was a servant of the temple and tabernacle establishment of God, and seems to have been highly motivated by love and obedience for God’s laws and ways. Therefore, unlike Uzza and the Philistines, the Ark of the Covenant became a blessing for him while it was a cursing to those who did not respect God’s ways. What is a curse to the disobedience can be a blessing to the people of God. Some objects and situations (such as this one) are important because they help to distinguish between the godly and the ungodly, as well as to teach leaders (like David) a lesson in obedience as well as in avoiding superstitious beliefs like the Ark of the Covenant being a curse. Clearly, the ark of the Covenant was not a curse to Obed-Edom and his family, and once David understood that the Ark of the Covenant was brought according to God’s law into the City of David with singing and rejoicing. And we can thank the Sons of Korah for an important role in teaching that lesson to King David, even if they remain obscure today. We also ought to be open to seeing what situations in our own lives may not be curses as we might initially think, but might be used by God to distinguish between the ungodly and godly around us.
