Plēroō: Getting the Full Picture

 

Then what had been spoken through Jeremiah the prophet was fulfilled.

Matthew 1:17 NASB

 

As we listen to the Christmas story—through songs, worship services, and Scripture readings—one phrase keeps appearing. Ironically, it is also one of the most frequently overlooked:

“To fulfill what was spoken by the prophet.”

Christmas cards tend to highlight the dramatic moments: a star hovering over a manger, angels filling the sky, shepherds kneeling in awe. But they rarely picture this phrase. That’s unfortunate, because the birth of Jesus becomes even more astonishing when we recognize that it fulfills an entire constellation of Old Testament promises.

The Greek word translated “fulfill” helps us see just how intentional—and how miraculous—the Bethlehem story really is.

 

The Greek Word

The Greek verb πληρόω (plēroō) [play-RAH-oh] occurs more than 80 times in the New Testament. Matthew alone uses it 12 times, more than any other Gospel writer. That is no accident. Matthew is making a sustained argument: Jesus is the promised King, the Messiah Israel had been waiting for.

Plēroō is a rich word with a broad range of meanings. Before focusing on its use in prophecy, it helps to see how the word functions elsewhere in the New Testament.

 

The Range of Meaning

1. To fillsomething literally

Plēroō can describe filling a physical object.

• Jesus spoke of a fishing net that was filled with fish (Matthew 13:48).
• When Mary poured perfume on Jesus’ feet, “the house was filled with the fragrance” (John 12:3).

2. To completea period of time

The word can refer to time reaching its full measure.

• Jesus predicted that Jerusalem would be trampled “until the times of the Gentiles are fulfilled” (Luke 21:24).
• Paul remained imprisoned in Caesarea until “two years were completed” and a new governor reopened his case (Acts 24:27).

3. To completea task or mission

Plēroō can describe finishing task or project.

• Paul said he had completed the proclamation of the gospel throughout the eastern Roman Empire and was now ready to travel west (Romans 15:19).

4. To be filled with a quality or influence

The word is often used metaphorically for inner character or control.

• Jesus spoke of being filled with joy, and promised the same fullness of joy to His followers (John 3:29; 15:11; 16:24).
• Believers are commanded to be filled with the Spirit (Ephesians 5:18)—not as water fills a container, but in the sense that the Spirit becomes the controlling influence of life.

 

Fulfilled Prophecy

One of the most significant uses of plēroō—especially in Matthew—is its connection to fulfilled prophecy. Matthew repeatedly points out that events in Jesus’ life did not happen randomly; they happened to fulfill what God had already spoken.

Here are the passages where Matthew explicitly uses plēroō to describe fulfillment:

• A child born to a virgin (Matthew 1:22)
• The family’s move to Egypt (Matthew 2:15)
• The mourning for the children of Bethlehem (Matthew 2:17)
• The move to Nazareth (Matthew 2:23)
• The beginning of ministry in Galilee (Matthew 4:14)
• Jesus’ healing ministry (Matthew 8:17)
• Ministry extending into Gentile territory (Matthew 12:17)
• Teaching through parables (Matthew 13:35)
• The triumphal entry into Jerusalem (Matthew 21:4)
• The betrayal and arrest of Jesus (Matthew 26:54, 56)
• The thirty pieces of silver (Matthew 27:9)

This list does not exhaust the fulfilled prophecies in Matthew—but these are the ones that explicitly use plēroō.

 

What Difference Does Plēroō Make?

Imagine standing in a synagogue one year before Bethlehem. The prophets are read aloud. Promises of an anointed deliverer echo through the room. But questions remain. When? How? Who? Even the prophets themselves longed to understand more fully what they had written (1 Peter 1:10–12).

Those promises were real—but incomplete. They were waiting.

After Bethlehem, everything changes. We can look back at those same passages and say:

“God did it. We can see how He brought it to pass.”

Because God fulfilled those prophecies with precision and faithfulness, we can face the future with confidence. The same God who fulfilled the first promises will surely fulfill the rest.

 

 

Study Hint:

Greek words often have multiple meanings, but a word has only one meaning in a given context. Plēroō illustrates this principle well. While it can mean “fill,” “complete,” or “bring to fullness,” our focus here has been on its use in fulfilled prophecy. The other meanings are worth studying—but that will have to wait for another time.

 

Coming Up

Next week we’ll turn to a key word in the Gospel of Mark. Again and again, Mark tells us that Jesus acted “immediately.” As we examine the Greek word behind that term, we’ll gain fresh insight into the urgency and authority of Christ’s ministry.
