Even if it was truly was, humans are still faillible:

• the texts are transcripted thousands of times, and errors made during transcriptions are eventually reproduced.
• the texts can be modified voluntarily during retranscriptions, maliciously or not.
• parts of texts are lost and found again.
• texts reference other extinct texts or what was considered common knowledge that was not written down. So we can only infer from there.
• Hebrew uses an abjab alphabet, which means no vowels, so certain written words can be different depending on what vowels you ascribe to them.
• texts are translated by people with biases and objectives as to what it should convey (like the US Evangelicals with the NIV).
• etc.

So even if the original text was given divinely, it would end up being distorted.

This is why I'm not comfortable saying the Bible is okay with abortion. It can be interpreted that way, for sure, but it's not a definite statement.
