Years ago, when our children were young, my husband made up actions to this song to teach our children one night at family night. It was an instant hit and i have since taught the children in primary. They learned it immediately and often request this song.
Here we go: i'll try to be as visual as possible...
-The Lord commanded Nephi (raise hands over your head towards heaven as if receiving instruction from Heaven)
-to go and get the plates (hold out your hands like for Book of Mormon stories)
-from the wicked laban (scrunch up your face into a mean look and place your hand over your eyebrows and then pan the room while singing)
-inside the city gates (with palms facing you, touch the tips of your nails of one hand to the tips of another to make a gate)
-Laman and Lemuel believed he should not try (open one arm to the side when you say each name.
-Nephi was courageous, this was his reply (flex muscles with arms bent at the elbow into a 90 degree angle)
-I will go, i will do (pump your left fist across your body for "I will go" and the right fist across to your left side for "I will do")
-the things the Lord commands (same as the beginning...arms up towards heaven)
-I know the Lord provides a way (take your arms down from heaven and have them form a path to one side of you)
-he wants me to obey (fold arms)
I hope this makes sense. It has been a great way for our primary to learn this song and it was nice to teach a song without printed visuals for a change.
If you're interested, I'll post actions to the 2nd verse later....
