The meaning is, not that they sacrificed oxen and fatlings every six steps, which would have been impossible, but that when - after the arrangement made by David for the Levites to carry the ark 1 Chronicles 15:2, 1 Chronicles 15:12, 1 Chronicles 15:15 they had borne it successfully and with visible tokens of God’s favor, out of the house of Obed-edom and six “steps” on the road to the city of David to the sound of the musical instruments - then they stopped and offered solemn sacrifices. Possibly “the step” may have had a technical sense, and denoted a certain distance, say a stadium. Six such distances would have been nearly a mile, and if the ground was difficult and steep, the successful progress of “those that bare the ark,” so far, would have been a fit cause for a thanksgiving sacrifice.
