When I look at your heavens, the work of your fingers,

the moon and the stars, which you have set in place,

what is man that you are mindful of him,

and the son of man that you care for him?

When I consider your heavens,

the work of your fingers,

the moon and the stars,

which you have set in place,

what is mankind that you are mindful of them,

human beings that you care for them?

When I observe your heavens,

the work of your fingers,

the moon and the stars,

which you set in place,

what is a human being that you remember him,

a son of man that you look after him?

When I look at the night sky and see the work of your fingers—

the moon and the stars you set in place—

what are mere mortals that you should think about them,

human beings that you should care for them?

When I look at your heavens, the work of your fingers,

the moon and the stars which you set in place—

what is a human being that you think of him?

and a child of humankind that you care for him?

When I consider thy heavens, the work of thy fingers,

The moon and the stars, which thou hast ordained;

What is man, that thou art mindful of him?

And the son of man, that thou visitest him?
