4. They were compared to oxen, because they were clean; for the ox was a clean beast. Hence the apostles are called holy. They were compared to oxen, because the ox is strong; and they also were mighty in the word (Prov 14:4; 2 Cor 12:12).
5. The ox will not lose what he has got by drawing; he will not let the wheels go back; so the apostles were set to defend, and not let that doctrine go back, which they had preached to others; nor did they, they delivered it pure to us.
6. One of the cherubs of which you read in the vision had a face like an ox, to show that the apostles, these men of the first order, are most like the angels of God (Eze 1:10).
7. In that they stood with their faces every way, it was, as I said, to show how the apostles should carry the gospel into all the world (Matt 28:19,20; Mark 16:15-18).
8. And observe, just as these oxen were placed looking in the temple every way, even so stand open the gates of the New Jerusalem to receive those that by their doctrine should be brought into it. 'And they shall come from the east, and from the west, and from the north, and from the south, and shall sit down in the kingdom of God' (Luke 13:29; Rev 21:13,14).
9. These oxen bear this molten sea upon their backs, to show that they should be the foundation workmen of the gospel, and that it ought not to be removed, as was the molten sea of old, from that basis to another.
10. It is also said concerning those oxen that thus did bear this molten sea, that all their hinder parts were inwards, that is, covered by that sea that was set upon their backs; their hinder parts, or, as the apostle has it, 'our uncomely parts' (1 Cor 13:23,24).
11. And, indeed, it becomes a gospel minister to have his uncomely parts covered with that grace which by the gospel he preached unto others. As Paul exhorts Timothy to take heed unto himself, and to his doctrine (1 Tim 4:6).
12. But alas! there are too, too many who, can they but have their hands covered with a few gospel notions, care not though their hinder parts are seen of all the world. But such are false ministers; the prophet calls them 'the tail.' 'The prophet that speaketh lies, either by word or with his feet, he is the tail' (Isa 9:15; Prov 6:12,13).
13. But what a shame is it to hide his head under this molten sea, while his hinder parts hang out. Such an one is none of Christ's oxen; for they, with honour to their Master, show their heads before all the world, for that their hinder parts are inward, covered.
