This verse is almost identical with 26.6. Only the verbs are different he made, (he) coupled, and (it) was. The singular he made, however, should be changed to “they made” on the basis of verse 8. Coupled is better rendered as “joined” (New Revised Standard Version). One whole means “one piece.” New International Version has “so that the tabernacle was a unit.”
