This is an-other thing I didn't notice until I started looking into the notation: the choral parts are written in such a way that "deliver" and "delight" are sometimes sung simultaneously. I'm not sure if there's any religious meaning behind this, but there's at least a poetic one, since "deliver" and "delight" exhibit consonance.
Later in this section, there's a melisma on one of the "delight"s so that it sounds like a laugh. It's similar to the previous section (All they that see him laugh him to scorn) in that it's a musical effect to portray laughing and it's an-other way in which Christ was mocked.
