Following the instructions in the video, I went to Psalm 34:1 (ESV and NASB), right-clicked on "bless", chose Lemma on the right and then Bible Word Study on the left. I went to the Grammatical Relationships section and did not find an entry for the target word (in the Hebrew text the word is in verse 2).
I did the same thing with the word "magnify" in verse 3 and had the same results - no entry in Grammatical Relationships.
Am I doing something wrong? Am I looking for something not supported by this function? Is there a problem with the resource tags or the Grammatical Relationships function?
