"If you know these things, blessed are you if you do them."
Isa 1:19, 20
"If you are willing and obedient, you shall eat the good of the land; 20 but if you refuse and rebel, you shall be devoured by the sword; for the mouth of the Lord has spoken."
1 Sam 15: 22 b, 23 a
Behold, to obey is better than sacrifice, and to hearken than the fat of rams. 23 For rebellion is as the sin of divination, and stubbornness is as iniquity and idolatry.
James 1: 22
But be doers of the word, and not hearers only, deceiving yourselves.
James 4:17
Whoever knows what is right to do and fails to do it, for him it is sin.
