Multiple Old Testament passages refer to a land flowing with milk and honey (Ex. 3:8, Lev. 20:24, Num. 14:8, etc). There are a lot of details that could be explained regarding this phrase, but the central theme is the idea of a Promised Land that would be received. While in the Old Testament it may be referring to a land promised to the Israelites, we as Christians today also have a Promised Land to look forward to – heaven! #ThanksForAsking!
