Seven Judgments Against The Neighbouring Nations, Including Judah (Amos 1:3 to Amos 2:5).
The announcing of YHWH's judgments on seven nations (including Judah) can be looked at in two ways. First it was an assurance to Israel that YHWH was watching over their basic interests and had observed the behaviour of the nations round about. By this he was gaining their interest. But even more importantly, as the inclusion of Judah brings out, Amos was cleverly gaining Israel's consent to his message as they approved of what God was doing to those nations (we can see them nodding their heads with approval as each judgment is pronounced), with the result that when he suddenly slid the knife in and showed them that they too were coming under YHWH's judgment his words would have hit home.
Lest Israel think that they were alone in coming under YHWH's judgment Amos first outlined the judgment coming on the surrounding nations. It was a poignant reminder to them that in spite of their behaviour YHWH had been watching over their interests, in that He had noted the ill-treatment meted out to them by their neighbours. These were depicted in a sevenfold group of prophecies, each one following a similar pattern. The judgments would come respectively on Damascus, Philistia, Tyre, Edom, Ammon, Moab and, last but not least, Judah, and it is apparent from this that it includes all the nations immediately surrounding Israel. They were also the nations who either dwelt in the original inheritance given to Israel (Philistia, Aram, Tyre and Judah), or had had their land specifically given to them by YHWH (Edom, Ammon and Moab). They all came within YHWH's sphere of activity (compare Psalms 60:8). Apart from Moab and Judah judgment was to come on them because of their continual bestial behaviour towards Israel. In the case of Moab it was for more general barbarism towards a related tribe. In the case of Judah it was because they had strayed from the Law of YHWH.
The nations in question were probably given in the order of the severity of the treatment that they meted out towards Israel and Judah, with Aram being the most severe, followed by Philistia and then Tyre, with Moab the least severe (nothing is in fact indicated about Moab's behaviour towards Israel). Others have seen a geographical pattern commencing in the north east (Aram), moving to the south west (Philistia, with four cities involved), going up to the north east (Tyre), and finally dealing with the three small nations in the south east (Edom, Ammon, Moab). But all had to be included for the point of the oracles was of YHWH's concern for the whole land that had been originally promised to Abraham and allocated to Israel, combined with the land of their acknowledged relatives, Edom, Moab and Ammon, which had specifically been given to those nations by YHWH for Lot's sake (Deuteronomy 2:5; Deuteronomy 2:9; Deuteronomy 2:19). And the point was that that whole area was to be devastated because it had come short of YHWH's most basic requirements. That is why all the nations bordering on Israel were included. YHWH's judgments would not be restricted. They would be ‘universal' to the whole area.
It will be noted that each description dealing with a nation commences with the refrain ‘thus says YHWH'. Nothing of what Amos warns about will come about accidentally Rather he is stressing that because YHWH has spoken, His word will actively go forth to accomplish His purpose (Isaiah 55:11) This declaration is then in each case followed by the reason why YHWH was acting. It was because of their multiplied transgressions. ‘For three transgressions, and for four, of --- I will not turn away their punishment because ---'. Three transgressions (three is the number of completeness) would be seen as fullness of transgression. To add a fourth was therefore to be excessive. It represented overflowing and continual transgression. The pattern then goes on to outline what they are being punished for (‘because --'), and in each case it is for some particularly heinous act of inhumanity of a type which would be condemned by all decent nations. This is then followed up with the threat of ‘fire' on the transgressor, accompanied in all cases except Tyre, Edom and Judah by a further threat and a further assurance that it was what YHWH had spoken. The exception in the case of Tyre and Edom was probably in order to link Philistia, Tyre and Edom together because they were involved together in their inhuman slave-trading. Judah was excepted because it would still have a future. YHWH would not forget His covenant with David, therefore those who ‘held the sceptre' would not finally be cut off in Judah's case. ‘Fire' was a regular means of divine judgment (Deuteronomy 16:13; Joshua 6:24; Joshua 8:8; Joshua 11:9), and may have included the thought that they were being ‘devoted as offerings to YHWH' (compare Numbers 31:10; Deuteronomy 7:25-26; Deuteronomy 12:3; Judges 1:8).
