Biblical authors often referred to weights, measurements, and distances that certainly were understandable in their context, but are foreign today. For example in Luke 2, 12-year-old Jesus is separated from his parents and verse 46 states after three days Joseph and Mary find him in the temple. Why did it take so long to locate Him? Verse 44 contains a clue. After departing from the Feast of the Passover in Jerusalem they travelled a “day’s journey” before they noticed their son wasn’t with them.
I don’t know about you, but I don’t refer to a “day’s journey” in my normal vocabulary. So how far did they travel? Fortunately for us there’s a simple Interactive in Logos 7 which quickly converts biblical measurements to modern equivalents.
