Yeremia 34 : 14 Jeremiah chapter 34 verse 14

Mwisho wa kila mwaka wa saba kila mtu na amweke huru ndugu yake aliye Mwebrania, aliyeuzwa kwako na kukutumikia miaka sita utamwacha atoke kwako huru, lakini baba zenu hawakunisikiliza, wala hawakutega masikio yao.

At the end of seven years you shall let go every man his brother who is a Hebrew, who has been sold to you, and has served you six years, you shall let him go free from you: but your fathers didn't listen to me, neither inclined their ear.
