Ruth 4:11

And all the people that were in the gate, and the elders, said, We are witnesses. The LORD make the woman that is come into thine house like Rachel and like Leah, which two did build the house of Israel: and do thou worthily in Ephratah, and be famous in Bethlehem:

All the people ... and the elders, said, We are witnesses. A multitude, doubtless, from curiosity or interest, were present on the occasion. There was no signing of deeds; yet was the transfer made, and complete security given, by the public manner in which the whole matter was carried on and concluded.

The Lord make the woman ... like Rachel and like Leah. This was the usual bridal benediction.
