In the wedding verses of the Rigveda and Atharvaveda the Gandharva Vishvavasu, second of the bride's three divine guardians, is praised and asked to rise and seek an unmarried girl.
Within the long wedding hymn, two verses (21-22) address Vishvavasu with praise and ask him to rise and find another maid in her father's house. Verses 40-41 tell the bride that Soma, the Gandharva and Agni were her lords before her human husband, each giving her to the next. The surrounding verses bless the road, free the bride from her father's house, and join the couple's hands.
The Atharvan wedding book repeats the three divine husbands, asks the Gandharvas and Apsarases who guard the wayside trees not to harm the procession, and sends Vishvavasu to the bride's unmarried sister and to his own wives the Apsarases, with homage to his eye and his fiery anger; it then declares the Gandharva banished to the farthest region. Hymn 4.37 drives Gandharvas and Apsarases away with the goat's-horn plant; 2.2 worships the Gandharva as lord of the world.
What is different here:
More wary: names his anger, the trees he haunts and where he should go, and states that he has been sent away.
