Quoting_commentary for Jeremiah 37:21

וַיְצַוֶּ֞ה הַמֶּ֣לֶךְ צִדְקִיָּ֗הוּ וַיַּפְקִ֣דוּ אֶֽת־יִרְמְיָהוּ֮ בַּחֲצַ֣ר הַמַּטָּרָה֒ וְנָתֹן֩ ל֨וֹ כִכַּר־לֶ֤חֶם לַיּוֹם֙ מִח֣וּץ הָאֹפִ֔ים עַד־תֹּ֥ם כָּל־הַלֶּ֖חֶם מִן־הָעִ֑יר וַיֵּ֣שֶׁב יִרְמְיָ֔הוּ בַּחֲצַ֖ר הַמַּטָּרָֽה׃

Then Zedekiah the king commanded, and they committed Jeremiah into the court of the guard, and they gave him daily a loaf of bread out of the bakers’street, until all the bread in the city was spent. Thus Jeremiah remained in the court of the guard.
