After Cain killed his brother Abel, and Cain cried to the Lord that the punish was more than he could bear, Moses wrote, “And the LORD said to him, ‘Therefore, whoever kills Cain, vengeance shall be taken on him sevenfold.’ And the LORD set a mark on Cain, lest anyone finding him should kill him” (Genesis 4:15).

The Lord had revealed Cain’s punishment, “So now you are cursed from the earth, which has opened its mouth to receive your brother’s blood from your hand. When you till the ground, it shall no longer yield its strength to you. A fugitive and a vagabond you shall be on the earth” (Genesis 4:11-12).

First, the Lord said that the ground would not yield its strength to Cain.

Second, Cain would be a fugitive and a vagabond on the earth.

His parents had already been kicked out of the Garden of Eden, and for Adam’s sin the Lord had also said that man would have to work hard to be able to eat, and thorns and thistles would be a problem.

Cain realized that working the earth would be even more difficult for him than it already had been.

That would lead to a life on the run.

It seems odd that Cain thought that was unbearable, after all, he had killed his brother, and lied to God!

However, if anyone killed Cain, such a person would suffer sevenfold, that is, seven times more than what Cain would experience.

We always reap more than we sow, whether it is something good or evil we have sown.
