John Gill Commentary 1 Kings 4:25

"And Judah and Israel dwelt safely, every man under his vine and under his fig-tree, from Dan even to Beer-sheba, all the days of Solomon." — 1 Kings 4:25 (ASV)

And Judah and Israel dwelt safely
Without fear of any injury done to their persons or properties by any enemy; which is, and will be, more abundantly fulfilled in Christ, the antitype of Solomon, (Jeremiah 23:5) ;

every man under his vine, and under his fig tree ;
which were principal trees in the land of Judea, put for all the rest; and the phrase denotes the happy, safe, quiet, full, and peaceable enjoyment of all outward blessings, and is used of the times of the Messiah, (Micah 4:4) ;

from Dan even to Beersheba ;
which were the two extremities of the land of Israel, north and south:

all the days of Solomon ;
so long this peace and safety continued, there being no wars in his time.
