Come Thou Fount

The first paragraph doesn't really have any allusion that I can see. Ebenezer in the dictionary is a memorial of divine aid. So the first line of the second paragraph could mean honoring the Lord. When I hear line five paragraph two I think of the good Samaritan. like the story of the good Samaritan this song speaks of Jesus saving us. Most of the other allusions are similar. Like line one paragraph three , it says "O to grace how great a debtor". The song is referring to Christs sacrifice.
