26: 1 Don't shake: Literally it means "I will never fall". The poet does not waver because of his firm trust in God.
Examine me, test me, refine me: carefully monitor the poet's heart, just as a jeweler values precious jewelry. "Tempering", God does not see enough, please correct me. Convey the poet's extremely humble message. God practices saints until they are fully sanctified (1 Peter. 1:7).

David didn't show off his righteousness. Even if his enemies surrounded him, he was determined to rely on God alone.

26: 10 evil ... bribery: the two are inseparable. The wicked always plot evil plans first, and then pay bribes specifically.
