Words in "Hark the Herald Angels" SUDDEN DEATH

I remembered "laid" being there, as in "mild he laid his glory by" but it's "lays" so my bad. As for "seed" here in verse 4: "Come, Desire of nations, come,

fix in us thy humble home;

rise, the woman’s conquering Seed,

bruise in us the serpent’s head." (https://www.lyricsforchristmas.com/christmas-carols/hark-the-herald-angels-sing/)
