'Hearkening' in the Bible

And all the multitude did keep silence, and were hearkening to Barnabas and Paul, declaring as many signs and wonders as God did among the nations through them;

Seeing therefore it remains that some enter into it, and those who first received the glad tidings did not enter in on account of not hearkening to the word,

Let us therefore use diligence to enter into that rest, that no one may fall after the same example of not hearkening to the word.
