Yahweh sends abundant rain (Joel 2:23-2:24)

“O children of Zion!

Be glad!

Rejoice in Yahweh!

Your God!

He has given

The early rain

For your vindication.

He has poured down

For you

Abundant rain,

The early,

As well as the latter rain,

As before.

The threshing floors

Shall be full of grain.

The vats shall overflow

With wine.

The vats shall overflow

With oil.”

Joel reminded the children of Zion that they should rejoice and be glad in Yahweh, their God, because he has given them plenty of rain, both the early and later rain, just like before the locust attack. Thus, the threshing floors would be full of grain. The vats or containers for the wine and the oil from the vines and trees would be overflowing.

Honor Yahweh (Prov 3:9-3:10)

“Honor Yahweh

With your substance.

Honor Yahweh

With the first fruits of all your produce.

Then your barns will be filled with plenty of wheat.

Your vats will be bursting with wine.”

If you honor Yahweh with your goods, and especially the first fruits of your harvest, then your barns will be filled with wheat and other crops. Your vats will be bursting with wine. It seems that this was an agricultural society with wheat and grapes as the dominant crop.
