Darby Bible Notes

word - Apeitheo. see Note, John 3.36. 'Who had not hearkened to the word' is, I apprehend, the true force here. It is taken from the LXX, Num. 14.43 and Deut. 1.26, which refer to the occasion on which God declared their carcases should fall in the wilderness.

KJV

18 And to whom sware he that they should not enter into his rest, but to them that believed not?
