I have gone astray like a lost sheep:
Seek thy servant:
For I do not forget thy commandments.
The Fifteenth Psalm I should call a short didactic lyric. Its title is The Good Citizen. It begins with a question:
Lord, who shall abide in thy tabernacle?
Who shall dwell in thy holy hill?
This question is answered by the description of a man whose character corresponds to the law of God. First there is a positive sketch in three broad lines:
He that walketh uprightly,
And worketh righteousness,
And speaketh truth in his heart.
