Illustrating an incident where, being hungry, Jesus approached a fig bush in leaf, expecting fruit even though it wasn’t the season for figs. Finding only leaves, Jesus declared, “May no one ever eat fruit from you again.” Subsequently, as he entered Jerusalem, Jesus drove out those engaged in commerce within the temple, calling it a house of prayer for all nations. This led to conflict with religious authorities seeking his demise. 

The next day, Peter observed the withered fig tree, prompting Jesus to emphasize the power of faith in prayer. He connected faith with the ability to move mountains, encouraging a belief that prayers, when offered without doubt, would be answered. Jesus underscored the importance of forgiveness in prayer, emphasizing that holding grudges could hinder one’s own forgiveness from the heavenly Father.

“The next morning as they were leaving Bethany, Jesus was hungry.  He
noticed a fig tree in full leaf a little way off, so he went over to see if he could
find any figs. But there were only leaves because it was too early in the
season for fruit. 
Then Jesus said to the tree, “May no one ever eat your fruit
again!” And the disciples heard him say it.
When they arrived back in Jerusalem, Jesus entered the Temple and began
to drive out the people buying and selling animals for sacrifices. He knocked
over the tables of the money changers and the chairs of those selling
doves,  and he stopped everyone from using the Temple as a marketplace.
He said to them, “The Scriptures declare, ‘My Temple will be called a house
of prayer for all nations,’ but you have turned it into a den of thieves.”
When the leading priests and teachers of religious law heard what Jesus
had done, they began planning how to kill him.
But they were afraid of him
because the people were so amazed at his teaching.
That evening Jesus and the disciples left the city.
The next morning as they passed by the fig tree he had cursed, the disciples
noticed it had withered from the roots up.” 
( Mark 11 : 12–20 ) 

 Jews who reject belief in Jesus are likened to a fig bush in the Bible that fails to yield fruit.

Then Jesus told this story: “A man planted a fig tree in his garden and came
again and again to see if there was any fruit on it, but he was always
disappointed. 
Finally, he said to his gardener, ‘I’ve waited three years, and
there hasn’t been a single fig! Cut it down. It’s just taking up space in the
garden.’
“The gardener answered, ‘Sir, give it one more chance. Leave it another year,
and I’ll give it special attention and plenty of fertilizer. 
If we get figs next
year, fine. If not, then you can cut it down.’” ( Luke 13:6 ).

During a gesture of generosity, Abigail quickly prepared a provision for David and his men. The offering included essential items such as bread, wine, sheep, and roasted grain, as well as delicacies like raisins and pressed figs. This reflects the common use of figs as a valued and nutritious food item during that period. 

“Abigail wasted no time. She quickly gathered 200 loaves of bread, two wineskins full of wine, five sheep that had been slaughtered, nearly a bushel of roasted grain, 100 clusters of raisins, and 200 fig cakes. She packed them on donkeys.”
( 1 Samuel 25:18 )

A fig bush poultice proves effective for applying warmth to boils, 

“Then Isaiah said, “Make an ointment from figs.” So Hezekiah’s servants spread the ointment over the boil, and Hezekiah recovered!” ( 2 Kings 20:7 ) 

It is noted that Zacchaeus climbed a fig bush to catch a glimpse of Jesus. 

“He tried to get a look at Jesus, but he was too short to see over the crowd. So he ran ahead and climbed a sycamore fig tree beside the road, for Jesus was going to pass that way. “( Luke 19:4.)
