Song credit to Eric Graef (https://www.youtube.com/watch?v=HzlaRLOA2Sg&t=80s). I used the same tune to expand to verse 19 as well. We're learning these verses as part of the SwordGrip program (www.swordgrip.com).
Chords:
v17 - Am G C Dm F C G ...Am G C Dm F G...F C G F C G
v18 - C G Am F C G Am F
v19 - C G Am F C G Am F

Here's a playlist of the songs we've used/adapted/written to learn the verses: https://www.youtube.com/playlist?list...​
