A frequent misinterpretation treats this verse as a directive for believers to withhold blessings or greetings from others, especially adversaries, or as a curse on everyday agricultural work, overlooking its poetic imagery in Psalm 129 that curses Zion's haters with barrenness and isolation, not instructing human interactions but illustrating God's judgment on the wicked's unproductive malice against the faithful.
Psalms 129:8
King James Version (1769)
8 Neither do they which go by say, The blessing of the Lord be upon you: we bless you in the name of the Lord.
Psalms 129:8 portrays the complete futility and rejection of those who oppress God's people, likening their doomed efforts to grass on rooftops that withers before harvest; consequently, no passersby offer them blessings in the Lord's name, emphasizing divine vindication for Israel, who has endured affliction from youth yet remains unconquered by enemies through God's righteous intervention.
