Let heaven and earth praise him ... the seas

Here heaven and earth and the seas are spoken of as if they are people who are able to praise God. (See: rc://en/ta/man/translate/figs-personification)

the seas and everything that moves in them

It is implied that "Let ... praise him" should be understood here. Alternate translation: "let he seas and everything that moves in them praise him" (See: rc://en/ta/man/translate/figs-ellipsis)
