You are perceptive. :-)
Magen (Strong's 4043) is used in some really interesting contexts. 4 verses found containing 4043 & 3468.
I can't explain that one any better than the star! Chalk another one up to the His Spirit? Who knows. He knows.
What led you search this Strong's number (4043)? I found 63 uses of the word "megan" in the OT. To which 4 verses are you referring?
Also, are you using a Bible search program, or are you using a Strongs cross reference book, which lists the usage of various words? Which ones?
