15:15 If God places no trust in his holy ones,
if even the heavens are not pure in his eyes,

How can one born of a woman be pure?
25:5 If even the moon is not bright,
and the stars are not pure as far as he is concerned,
31:24 “If I have put my confidence in gold
or said to pure gold,
‘You are my security!’
