Jeremiah 15:5 - Ellicott's Commentary On The Whole Bible

To ask how thou doest? — This is a fair paraphrase of the original, but it wants the Oriental colouring of the more literal to ask after thy peace. As “Peace be with thee” was the usual formula of salutation, sc.,” Is it peace?” was the equivalent for our more prosaic question, “How do you do?” (Genesis 43:27; Judges 18:15). The same phrase meets us in Exodus 18:7, “They asked each other of their welfare,” literally, of their peace.
