Their legs were straight, and the soles of their feet were like the sole of a calf’s foot. And they sparkled like burnished bronze.
This seems added by way of explanation. Since Ezekiel has spoken of their human form, he adds that their feet were straight, although he calls them round or like those of a calf. I refer the straightness not to the feet only but also to the legs. It is therefore just as if he had said that these animals stood as men do.
The visions of God which Ezekiel here saw were very glorious, and had more particulars than those which other prophets saw. It is the scope and intention of these vision, 1. To possess the prophet's mind with very great, and high, and honourable thoughts of that God by whom he was commissioned and for whom he was employed.
Commenting on Ezekiel 1:4-14
And their feet were straight feet,.... And they went straight forward, as in Eze 1:12; they made straight paths for their feet, and walked uprightly, according to the truth of the Gospel; did not go into crooked paths, or turn to the right hand, or the left; and having put their hand to the plough of the Gospel neither looked back, nor turned back.
