There is a typo in 1 Kings 13:29 in the Holman Christian Standard Bible on the iPhone. It reads, "...The old prophet came into to the city...." According to all the other copies that I checked, it should read, "...The old prophet came into the city...."
The HCSB copy on the desktop version of Logos 4 does not have this error in it. I don't know of any other way to report iPhone typos, so I've done it here. Hopefully it can be corrected soon.

Paul
