'Self interest' in the Bible

It is better to focus on what you can see than to meander after your self-interest; this also is pointless and a chasing after wind.

For when a native Israeli or a resident alien abandons me to set up idols in his heart behind my back, and then places the stumbling block of his iniquity right in front of his own face, then approaches a prophet to inquire of me on behalf of his own self-interest, I, the LORD will answer him myself.
