The psalmist would not tolerate cheaters.

No one who practices deceit
    will dwell in my house;
no one who speaks falsely
    will stand in my presence.

-Psalm 101:7, NIV

When the Psalmist wrote this verse, he spoke into the context of emulating God’s character of love and justice (see Psalm 101:1).

One thing is true about all cheaters:

All Cheaters lie and practice deceit.

This means they are not eligible for the presence of the righteous Psalmist here. We see here a precedent for not tolerating this sort of sinful behavior. This is a picture of how godly people handle such sin.

Lying and deceit are not tolerated by those who profess to honor and follow God.
