Where do you get that David was 5'2"? Source please.
Hi Brad,
Thanks for your question. The sources for everything in the David and Goliath graphic you asked about are in the full-length article here: http://www.biblestudymagazine.com/interactive/goliath/
The graphic in the full length article specifies that David's height is an estimate based on the biblical text calling him a "young man" (1 Sam 9:2). We estimated his height from this note and archaeological evidence concerning the average height of Israeli men of the period.
One of our sources for the height of people in Israel is: G. Ernest Wright, “Troglodytes and Giants in Palestine,” Journal of Biblical Literature 57:3 (Sept 1938): 305-309.
We also consulted a few archaeologists of Israeli sites in that period via email.
