John Chrysostom : Then he adds, "When it is said, To-day if ye hear His voice, harden not your hearts, as in the provocation." This is a transposition, "when it is said, To-day if ye hear His voice, harden not your hearts." It must be read thus: "Let us fear lest a promise being left us of entering into His rest, any of you should seem to come short of it; for to us was the Gospel preached as well as unto them when it is said, To-day if ye hear His voice" (for "To-day" is "at every time"). Then he adds "but the word of hearing did not profit them, as they were not mixed by faith with them that heard." ... Now what he says is to this effect. They also heard, as we hear: but no profit came to them. Do not suppose then that by "hearing" what is proclaimed ye will be profited; seeing that they also heard, but derived no benefit because they did not believe. — Homily on Hebrews 6 Oecumenius : "As in the rebellion." Hyperbaton [ὑπερβατὸν] is: for we must understand it as "Let us fear." The surpassing thing; in what is said: Today, if you hear the voice, and the things following, let us fear, lest, a promise being left behind, and the things following. — The Pseudo-Oecumenian Catena on Hebrews
