Charles Ellicott Commentary Jeremiah 15:5

"For who will have pity upon thee, O Jerusalem? or who will bemoan thee? or who will turn aside to ask of thy welfare?" — Jeremiah 15:5 (ASV)

To ask how you are doing? —This is a fair paraphrase of the original, but it lacks the Eastern character of the more literal to ask after your peace. As “Peace be with you” was the usual formula of salutation, namely, “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.
