Job continues describing situations in which he would deserve God's punishment, but he knows they are not true. He does not finish his sentence in verses 16 and 17. Instead he explains in verse 18 why they are not true. (See: [[rc://en/ta/man/translate/figs-hypo]])
"If I have kept poor people from getting what they desire"
