Ruth 2:17-20

17So Ruth gleaned in the field until evening. Then she threshed the barley she had gathered, and it amounted to about an ephah. That is, probably about 30 pounds or about 13 kilograms

18She carried it back to town, and her mother-in-law saw how much she had gathered. Ruth also brought out and gave her what she had left over after she had eaten enough.

19Her mother-in-law asked her, “Where did you glean today? Where did you work? Blessed be the man who took notice of you!” Then Ruth told her mother-in-law about the one at whose place she had been working. “The name of the man I worked with today is Boaz,” she said.

20“The LORD bless him!” Naomi said to her daughter-in-law. “He has not stopped showing his kindness to the living and the dead.” She added, “That man is our close relative; he is one of our guardian-redeemers. The Hebrew word for guardian-redeemer is a legal term for one who has the obligation to redeem a relative in serious difficulty (see Lev. 25:25-55). ”
