This "Introduction" attempts to take account of this reciprocal relationship. The first part deals with the history of Israel. However, its approach differs from most accounts of this history. It takes the Old Testament texts themselves as a starting point and first of all outlines the picture of historical developments and associations which the texts present. An attempt is then made, on this basis, to reconstruct historical developments by introducing material from outside the Bible. This method of working leads to close connections between the second and third parts, because it has to take account of the nature and original purpose of the texts and their function within the biblical books as they are now. The second part attempts to present the texts collected in the Old Testament as expressions of the life of Israel. The third part discusses the books of the Old Testament in their present form.
