His going forth is from the end of the heaven
From the east, where it rises:
and his circuit to the ends of it;
to the west, where it sets; which is expressive of the large compass the Gospel administration took in the times of the apostles; whereby the grace of God appeared to all men, shone out in a very illustrious manner, and Christ became, what the sun is to the earth, the light of the world;
and there is nothing hid from the heat thereof;
though things may be hid from the light of it, yet not from its heat, so forcible and penetrating it is Christ, in the administration of the Gospel to all to whom it comes with power, not only enlightens their minds, but quickens their souls, warms their hearts, causes them to burn within them, arises with healing in his wings upon them, and makes his Gospel the savour of life unto life unto them. The psalmist goes on to say more and excellent things of the Gospel, its nature and usefulness.
