כֹּֽה־אָמַר֩ יְהוָ֨ה צְבָא֜וֹת אֱלֹהֵ֣י יִשְׂרָאֵ֗ל לָק֣וֹחַ אֶת־הַסְּפָרִ֣ים הָאֵ֡לֶּה אֵ֣ת סֵפֶר֩ הַמִּקְנָ֨ה הַזֶּ֜ה וְאֵ֣ת הֶחָת֗וּם וְאֵ֨ת סֵ֤פֶר הַגָּלוּי֙ הַזֶּ֔ה וּנְתַתָּ֖ם בִּכְלִי־חָ֑רֶשׂ לְמַ֥עַן יַעַמְד֖וּ יָמִ֥ים רַבִּֽים׃ (ס)
אַזױ האָט געזאָגט ה׳ פֿון צבָאומת, דער גאָט פֿון ישׂראל: נעם די דאָזיקע געשריפֿטסן, דעם דאָזיקן שטַר-מכירה, אי דאָס פֿאַרחתמעטע, אי דאָס דאָזיקע אָפֿענע געשריפֿטס, און זאָלסט זײ אַרײַנטאָן אין אַ לײמענער כּלי, כּדי זײ זאָלן האַלטן פֿיל טעג.

“Thus said the Lord of Hosts, etc.” [32:14]. Thus has God said: I have commanded this because you should buy the field and you should do this publicly in the hope that Israel should know that they will be redeemed from the exile and will again come to the land, to their fields and their houses. Therefore, the Holy One commanded him to buy the field, to comfort Israel that they should not think that they would be destroyed.1Radak, Jeremiah, 32:14.

So said, etc. Do not say that I am concealing them for nothing since everyone is going into exile.
