The lessons and words of God in the Bible, from old to new testament, does not contradict each other. Iba iba lang ang audiences kaya akala natin, nagkaka-iba ang teachings. Hence the Bible should be taken as a whole. Hindi pwedeng magkaiba ang utos and teachings in Diyos regardless of time.
Here's an example i have learned:
Det. 19:21
21 Show no pity: life for life, eye for eye, tooth for tooth, hand for hand, foot for foot.
Madalas ito ma-misinterpret para may personal reason tayo for revenge. Cherry picking eka. But if you would read the verses prior to that:
Det. 19:15-21
Witnesses
15 One witness is not enough to convict anyone accused of any crime or offense they may have committed. A matter must be established by the testimony of two or three witnesses.
16 If a malicious witness takes the stand to accuse someone of a crime, 17 the two people involved in the dispute must stand in the presence of the Lord before the priests and the judges who are in office at the time. 18
The judges must make a thorough investigation, and if the witness proves to be a liar, giving false testimony against a fellow Israelite, 19 then do to the false witness as that witness intended to do to the other party. You must purge the evil from among you. 20 The rest of the people will hear of this and be afraid, and never again will such an evil thing be done among you. 21 Show no pity: life for life, eye for eye, tooth for tooth, hand for hand, foot for foot.
This is a command for the judges pala. I think hindi applicable sa atin. Ang pagkaka-intindi ko, dapat equal weight ang punishment sa crime. Imagine na lang natin kung ang mga judges natin ay puro pity.
Which coincides with the new testament.
Matthew 5:38-42
Eye for Eye
38 “You have heard that it was said, ‘Eye for eye, and tooth for tooth.’[h] 39 But I tell you, do not resist an evil person. If anyone slaps you on the right cheek, turn to them the other cheek also. 40 And if anyone wants to sue you and take your shirt, hand over your coat as well. 41 If anyone forces you to go one mile, go with them two miles. 42 Give to the one who asks you, and do not turn away from the one who wants to borrow from you.
