Divrey Hayamim Bais 31:7 In-Context

5 And as soon as the devar went out, the Bnei Yisroel brought in abundance the reshit of dagan, tirosh, and yitzhar (pure olive oil), and devash, and of all the increase of the sadeh; and the ma’aser (tithe) of all things they brought in abundantly.

6 And concerning the Bnei Yisroel and Yehudah, that dwelt in the towns of Yehudah, they also brought in the ma’aser of bakar and tzon, and the ma’aser of kadashim which were hamekudashim (consecrated, set apart as kodesh) unto Hashem Eloheihem, and piled them in heaps.

7 In the chodesh hashelishi they began to lay foundations for the heaps, and completed them in the chodesh hashevi’i.

8 And when Chizkiyahu and the sarim came and saw the heaps, they blessed Hashem, and His Am Yisroel.

9 Then Chizkiyahu questioned the Kohanim and the Levi’im concerning the heaps.
