(According to the metrical classification, there's only one line here; but the text is formatted as two separate lines.)
In the sixth verse, the text here is "Yea, whate'er / I here must bear." The sense is completed with the following lines: "Thou art still my purest pleasure, / Jesus, priceless treasure!" One of the syllables of "whate'er" is sung to an accidental (Ab), and because this pitch is outside of the tune's key (G minor), there's something of a sense of the breadth that "whate'er" entails.
