What fact in the history of joash is significant to the history of redemption? a) he typified christ. b) he preserved david's lineage. c) he wrote salvation psalms. d) he was a great prophet.

I had an answer all typed out and ... somehow it got lost. There were 2 Joash's one was very good. He ruled for 40 years. His monarchy was Judah. The other one was quite a rotten dude. He ruled for 16 years. Given your question, the short answer is A. But there is something most interesting about him: he is not listed in the lineage from David to Jesus. There were 3 other kings that were not listed either. Joash is not mentioned in Luke 3 either.

He is not given credit for any psalms, nor was a prophet. It is true that he preserved David's lineage, but I somehow do not think that is the nature of your question. If left to my own devices, I would answer that he was righteous and that preserved the line from David to Jesus.

However your question suggests that he typified Christ. I would pick that, but don't be surprised if it is B.
