And Jeroboam instituted a religious festival in Bethel, held on the fifteenth day of the eighth month, in imitation of the annual Festival of Shelters in Judah. There at Bethel he himself offered sacrifices to the calves he had made, and he appointed priests for the pagan shrines he had made.
For this is what the Lord of Heaven’s Armies, the God of Israel, says: In your own lifetime, before your very eyes, I will put an end to the happy singing and laughter in this land. The joyful voices of bridegrooms and brides will no longer be heard.
I will take away your happy singing and laughter. The joyful voices of bridegrooms and brides will no longer be heard. Your millstones will fall silent, and the lights in your homes will go out.
I will put an end to the happy singing and laughter in the streets of Jerusalem. The joyful voices of bridegrooms and brides will no longer be heard in the towns of Judah. The land will lie in complete desolation.
In that day the singing in the temple will turn to wailing. Dead bodies will be scattered everywhere. They will be carried out of the city in silence. I, the Sovereign Lord, have spoken!”
You can’t wait for the Sabbath day to be over and the religious festivals to end so you can get back to cheating the helpless. You measure out grain with dishonest measures and cheat the buyer with dishonest scales.
