Commentators explain this verse as a poetic summary of locating the Ark of the Covenant. "Ephrathah" is identified as Bethlehem, David's hometown, where the plan to move the Ark was likely discussed or "heard of." The Ark itself was then "found in the fields of the wood," a reference to Kirjath-jearim (which means "city of woods"), where it had rested for decades. The verse recounts the successful effort to bring God's symbolic presence to Jerusalem.
