Their Redeemer is strong; the Lord of hosts is his name: he shall throughly plead their cause, that he may give rest to the land, and disquiet the inhabitants of Babylon. (Jeremiah 50:34)
Heb. go’el. This word appears more than 40 times in the OT, although Jeremiah uses it only here. It is variously translated by the KJV as “redeemer,”“kinsman,”“revenger,”“avenger.” It is the term applied to the near relative whose duty it was to avenge a murder (see Num. 35:19), and to buy back land sold by a poor man (see Lev. 25:23-25; cf. Ruth 3:9; see on Ruth 2:20). The Lord is here presented as Israel’s kinsman, who will both avenge her persecutors and restore her to her rightful inheritance.
