Ruth 4:14,15

And the women said unto Naomi, Blessed be the LORD, which hath not left thee this day without a kinsman, that his name may be famous in Israel. (15) And he shall be unto thee a restorer of thy life, and a nourisher of thine old age: for thy daughter in law, which loveth thee, which is better to thee than seven sons, hath borne him.

It was a very common thing in Israel, to offer pious salutations upon any auspicious events, and especially when the hand of the Lord was seen in them. That is a sweet instance, Luke 1:42; Luke 1:45
