Hebrews 3 · a question people ask

"so long as it is called “today”" (3:13). How long is that?

In the text

Here are the letter's own words: "but exhort one another day by day, so long as it is called “today”, lest any one of you be hardened by the deceitfulness of sin." (3:13). The verse gives no number of days or years, and these notes give none. They say no more of how long it lasts than the verse's own words.

The verses

“but exhort one another day by day, so long as it is called “today”, lest any one of you be hardened by the deceitfulness of sin.”
Hebrews 3:13 · World English Bible

From Favor's study of Hebrews 3

Hebrews 3: Exhort one another day by day

The words "Today if you will hear his voice" come twice in Hebrews 3 (3:7, 3:15), and between them the letter speaks today to its own readers: "exhort one another day by day, so long as it is called “today”" (3:13). And behind rebellion (3:8, 3:15) and rebelled (3:16) are a Greek noun and the verb Strong's gives it as coming from, which the New Testament has nowhere else.

In Favor, questions like this come up right where they arise as you read, with the Hebrew and Greek behind the words and how the chapter leads to Jesus.
