John Gill Commentary Psalms 92:5

"How great are thy works, O Jehovah! Thy thoughts are very deep." — Psalms 92:5 (ASV)

O Lord, how great are your works!
&c.] Of nature, providence, and grace, both for quantity and for quality, for number, excellency, and glory, as they are a display of God's wisdom, power, and goodness; see (Psalms 104:24) ,

and your thoughts are very deep ;
his counsels, purposes, and designs, they are unfathomable and unsearchable; see (1 Corinthians 2:10) .
