These kind of people become hardened in their hearing, hardening their hearts (Exodus 8:15,32; 9:17,34;Pr28:14; Romans 1:18-20; Hebrews 3:12-15; Zechariah 7:12).
Watu wa aina hii hufanywa kuwa wagumu kwenye kusikia kwao na kwenye mioyo yao (Kut 8:15, 32; 9:17, 34;Pr28:14; Rum 1:18-20; Ebr 3:12-15; Zek 7:12).
