Jeremiah 50:34

Redeemer - i. e., גאל gā'al. Yahweh is Israel’s next relative, bound by law to avenge him, as well as to ransom him from captivity. It was the Go’el’s duty also to plead his kinsman’s cause. How thoroughly Yahweh will execute this duty for Israel is shown in the Hebrew by the triple repetition of the same word; literally “in pleading He will plead their plea.”

The land ... - Rather, “the earth.” Babylon has hitherto by its ambition kept the world in unrest: now by its fall men everywhere can dwell in security.
