# Jeshurun

This is another name for Israel. Translate it as in Deuteronomy 32:15. 

# who rides through the heavens ... in his majesty on the clouds

"who rides through the heavens like a king rides through a battlefield ... on the clouds like a king on his chariot"

# to your help

"to help you." Moses speaks to the Israelites as if they were one man, so the word "you" here is singular.
