When the angel tells Mary that she will have a baby, the angel concludes that no single word of God will fail. But what wouldn't fail, the word or what the word refers to?

We all recognize that there is not necessarily a Greek word behind every English word. Sometimes they are implied by another Greek word, or sometimes they are necessary so the translation does not miscommunicate. When Paul says that we are not to look after our own interests in Phil 2:4, does he really mean that?

Sometimes a Bible translator must alter the order of the Greek phrases so the English isn't confusing or miscommunicates. A good example is in 1 Thess 2:14. The majority of even the formal equivalent translations alter the phrase order, which illustrates why formal equivalent translations are not always transparent to the Greek.

This is a common question. People think the Greek New Testament says "brother," and translators therefore add to the Bible when they say "brother and sister." The fact of the matter is that the word "brother' is English, and the New Testament is written in Greek and says ἀδελφός. So the Bible, technically, does not say "brother." The real question is, what does ἀδελφός refer to and how do you convey the meaning in your culture?

Imperfects can be tricky to translate. Do you let the meaning of the word carry the aspect, is it a plain continuous idea, or one of the specialized uses of the imperfect such as the inceptive? Such is the challenge of translating imperfects.
