Hosanna

This word means "save us" but can also mean "praise God!" See how you translated this in Matthew 21:9.

the Son of David

This may be translated as "descendant of king David." However, "Son of David" is also a title for the Messiah, and the children were probably calling Jesus by this title.

they became very angry

Alternate translation: "they became very angry because people were praising him"
