The bread of God (ho artos tou theou). All bread is of God (Mat 6:11). The manna came down from heaven (Num 11:9) as does this bread (ho katabainōn). Refers to the bread (ho artos, masculine). Bernard notes that this phrase (coming down) is used seven times in this discourse (Joh 6:33, Joh 6:38, Joh 6:41, Joh 6:42, Joh 6:50, Joh 6:51, Joh 6:58).
Giveth life (zōēn didous). Chrysostom observes that the manna gave nourishment (trophē), but not life (zōē). This is a most astounding statement to the crowd.
