# Now

This word is used here to mark a break in the psalm. It transitions from the people speaking to the king speaking.

# I know

The word "I" probably refers to the king who is speaking in this section.

# his anointed one ... answer him

"me, his anointed one ... answer me"

# from his holy heaven

God dwells in heaven as well as in the temple in Jerusalem.

# with the saving strength of his right hand

"with his great strength he will rescue him"
