40 Heb “light”; but parallel to the moon it is the sun. This section speaks of false worship of the sun and the moon.
41 Heb “and my hand kissed my mouth.” The idea should be that of “my mouth kissed my hand.” H. H. Rowley suggests that the hand was important in waving or throwing the kisses of homage to the sun and the moon, and so it receives the focus. This is the only place in the OT that refers to such a custom. Outside the Bible it was known, however.
42 Heb “it.”
43 See v. 11 for the construction. In Deut 17:2ff. false worship of heavenly bodies is a capital offense. In this passage, Job is talking about just a momentary glance at the sun or moon and the brief lapse into a pagan thought. But it is still sin.
44 The verb כָּחַשׁ (kakhash) in the Piel means “to deny.” The root meaning is “to deceive; to disappoint; to grow lean.” Here it means that he would have failed or proven unfaithful because his act would have been a denial of God.

ESVEnglish Standard Version

“If I have made gold my trust

or called fine gold my confidence,

if I have rejoiced because my wealth was abundant

or because my hand had found much,

if I have looked at the sun when it shone,

or the moon moving in splendor,

and my heart has been secretly enticed,

and my mouth has kissed my hand,

this also would be an iniquity to be punished by the judges,

for I would have been false to God above.

NIVNew International Version (2011)

“If I have put my trust in gold

or said to pure gold, ‘You are my security,’

if I have rejoiced over my great wealth,

the fortune my hands had gained,

if I have regarded the sun in its radiance

or the moon moving in splendor,

so that my heart was secretly enticed

and my hand offered them a kiss of homage,

then these also would be sins to be judged,

for I would have been unfaithful to God on high.

CSBChristian Standard Bible

If I placed my confidence in gold

or called fine gold my trust,

if I have rejoiced because my wealth is great

or because my own hand has acquired so much,

if I have gazed at the sun when it was shining

or at the moon moving in splendor,

so that my heart was secretly enticed

and I threw them a kiss,

this would also be an iniquity deserving punishment,

for I would have denied God above.

NLTNew Living Translation

“Have I put my trust in money

or felt secure because of my gold?

Have I gloated about my wealth

and all that I own?

“Have I looked at the sun shining in the skies,

or the moon walking down its silver pathway,

and been secretly enticed in my heart

to throw kisses at them in worship?

If so, I should be punished by the judges,

for it would mean I had denied the God of heaven.

LEBThe Lexham English Bible

“If I have made gold my trust,

or I have called fine gold my security,

if I have rejoiced because my wealth was great

or because my hand found a fortune,

if I looked at the sun when it shone

or at the moon moving in splendor,

and I was secretly enticed,

and my hand threw them a kiss,

this also is an iniquity to be judged,

for I have deceived God above.

KJV 1900King James Version

If I have made gold my hope,

Or have said to the fine gold, Thou art my confidence;

If I rejoiced because my wealth was great,

And because mine hand had gotten much;

If I beheld the sun when it shined,

Or the moon walking in brightness;

And my heart hath been secretly enticed,

Or my mouth hath kissed my hand:

This also were an iniquity to be punished by the judge:

For I should have denied the God that is above.
