Is this the word of God ?

In the bible, a book that supposed to be inspired by God, we read:

2 Maccabees 1

1 From the Jews of Jerusalem and Judea to those in Egypt, warm greetings.

² May God be good to you and keep the covenant he made with Abraham, Isaac, and Jacob, his faithful servants.

2 Maccabees 15

38 And if I have done well, and as is fitting the story, it is that which I desired: but if slenderly and meanly, it is that which I could attain unto.

39 For as it is hurtful to drink wine or water alone; and as wine mingled with water is pleasant, and delighteth the taste: even so speech finely framed delighteth the ears of them that read the story. And here shall be an end.

2 Maccabees2

The topic was 5 books, however the person has "summarized" it:

23 All these things (I say) being declared by Iason of Cyrene in five books, we will assay to abridge in one volume.

24 For considering the infinite number, and the difficulty, which they find that desire to look into the narrations of the story, for the variety of the matter,

25 we have aimed to please those who wish to read, to make it easy for those who are inclined to memorize, and to profit all readers.

26 Therefore to us that have taken upon us this painful labour of abridging, it was not easy, but a matter of sweat, and watching.

27 Even as it is no ease unto him, that prepareth a banquet, and seeketh the benefit of others: yet for the pleasuring of many we will undertake gladly this great paines:

28 Leaving the responsibility for exact details to the historian, and confining our efforts to presenting only a summary outline.

29 For as the master builder of a new house, must care for the whole building: but hee that undertaketh to set it out, and paint it, must seek out fit things for the adorning thereof: even so I think it is with us.

30 It is the duty of the original historian to occupy the ground and to discuss matters from every side and to take trouble with details,

31 but the one who recasts the narrative should be allowed to strive for brevity of expression and to forego exhaustive treatment.

32 At this point therefore let us begin our narrative, adding only so much to what has already been said; for it is foolish to lengthen the preface while cutting short the history itself.

Quran 2:97:

فَوَيْلٌ لِّلَّذِينَ يَكْتُبُونَ الْكِتَابَ بِأَيْدِيهِمْ ثُمَّ يَقُولُونَ هَٰذَا مِنْ عِندِ اللَّهِ لِيَشْتَرُوا بِهِ ثَمَنًا قَلِيلًا ۖ فَوَيْلٌ لَّهُم مِّمَّا كَتَبَتْ أَيْدِيهِمْ وَوَيْلٌ لَّهُم مِّمَّا يَكْسِبُونَ

So woe to those who write the "scripture" with their own hands, then say, "This is from Allah ," in order to exchange it for a small price. Woe to them for what their hands have written and woe to them for what they earn.
