That's the meaning of the Hebrew word 'hallelu'. If you add 'yah' or more commonly in English 'jah' you've got 'Let Us Praise God'.
I knew a woman, a committed Jew, who lived her life surrounded by books and the love of art and literature and knowledge and Judaism in several different languages. She also spent her very long life not believing in the existence of a god.
I did not meet her until most of her amazing mind had betrayed her and most of her memory had abandoned her. She lived in a nursing home and said little except 'Good idea' in response to something of interest and 'Hallelu' when something really warranted her praise.
Never, though, did she say 'Halleluyah' because not even dementia could create in her a belief she did not possess.
Let us praise integrity.
Hallelu and Good idea.
