God assures us of the regular weeks of harvest

Jeremiah 5:20-31
You foolish and senseless people, who have eyes but do not see, who have ears but do not hear.
These people have stubborn and rebellious hearts; they have turned aside and gone away.
Your wrongdoings have kept these away; your sins have deprived you of good.
Should I not punish them for this? declares the Lord.
God who gives autumn and spring rains in season who assures us of the regular weeks of harvest.
Why?
People of Israel and Judah did not fear the Lord and turn away from the Lord,, wrongdoings and sins have turned aside and gone away from the bless of the Lord.
All of the season and the harvest are under blessing of the Lord.
Don't be a foolish and senseless man, careful watching and listening.
How?
Fear the Lord and worship his holy name.
