Hosanna

This word means "save us," but it can also mean "praise God!"

the son of David

Jesus was not David's literal son, so this may be translated as "descendant of king David." However, "Son of David" is also a title for the Messiah, and the crowd was probably calling Jesus by this title.

in the name of the Lord

Here "in the name" means "in the power" or "as a representative." Alternate translation: "in the power of the Lord" or "as the representative of the Lord" (See: rc://en/ta/man/jit/figs-metonymy)

Hosanna in the highest

Here "highest" refers to God who rules from the highest heaven. Alternate translation: "Praise God, who is in the highest heaven" or "Praise be to God" (See: rc://en/ta/man/jit/figs-metonymy)
