इहैव स्तं मा वियौष्टं विश्वमायुर्व्यश्नुतम् ।
क्रीळन्तौ पुत्रैर्नप्तृभिर्मोदमानौ स्वे गृहे ॥
Rigveda (10-84-42)
Actually this mantra talks about an ideal married life, or गृहस्थ आश्रम.
1.) The marriage should be between a husband and a wife. The mantra uses Dual Number signifying this. Thus, the Vedas do not propound many husbands or many wives.
