Are the terms Hebrews, Jews, and Israelites interchangeable?

TL;DR:

“Hebrew,” “Israelite,” and “Jew” refer to God’s people at different stages of their history. While the terms increasingly overlapped (especially by the New Testament period), they are not strictly interchangeable because each developed from a distinct historical and national context.

what does the bible say?

The terms “Hebrew,” “Israelite,” and “Jew” denote different periods in the historical development of Israel, from before the nation's formation through the period of exile. The meanings of the words overlap, particularly in later usage, but they are not merely different words for the same meaning.

“Hebrew” is the earliest of the three and likely a term used by outsiders or as an ethnic reference (e.g., Genesis 14:13, 34:32; Exodus 1:15–16; 1 Samuel 4:6, 9). Some have suggested that it derives from the earlier name “Eber” (Genesis 10:21–24), though that is debated.

“Israelite” refers to the people of the early nation of Israel. In Genesis 32:28, God renamed Jacob “Israel.” His children were referred to as the “sons of Israel” (Exodus 1:7 NASB). An Israelite, then, is a formal word for referring to those descended from Jacob.

“Jew” is a later word. Later in Israel’s history, it split into two kingdoms. The Northern Kingdom went into exile first, leaving just the Southern one, which was primarily the tribe of Judah. “Jew” referred to those from Judah. While it was used primarily during and after the exile (Esther 2:5; Zechariah 8:23; Nehemiah 1:2), it appears in a couple of pre-exile texts, such as Jeremiah 34:9.

In the New Testament, the three words began to overlap in meaning (Philippians 3:5; 2 Corinthians 11:22).

from the old testament

The words “Hebrew,” “Israelite,” and “Jew” represent different stages in the establishment and growth of God’s people. “Hebrew” is the earliest term, appearing as an early ethnic or clan identifier before Israel began forming as a nation. Abraham was referred to as “Abram the Hebrew” (Genesis 14:13). Joseph was called a “Hebrew” (Genesis 39:14), and the midwives were known as the “Hebrew midwives” (Exodus 1:15–16). It seems to have been used most often by foreigners or in cross-cultural settings (Genesis 34:32; 1 Samuel 4:6, 9). Some argue that Eber in the Genesis 10 genealogies is the root word for “Hebrews” (Genesis 10:21–24), but that is a heavily debated assertion.
“Israelite” referred to the “people of Israel” (Exodus 1:1). God renamed Jacob “Israel” after wrestling with him (Genesis 32:22–32), which God later confirmed as meaning that he was the start of the nation (Genesis 35:9–12). Jacob (Israel) had twelve sons, who would become the twelve tribes of Israel (Genesis 35:22–26). As the people grew in number and the nation began forming, they were known as Israelites (Exodus 1:7).
“Jew” refers to the tribe of Judah. After Solomon, David’s son, died, Israel, as a single nation, split into two kingdoms (1 Kings 12:16–20). The Northern Kingdom was known as Israel (1 Kings 12:20) and consisted of ten of the twelve tribes. It was eventually conquered by the Assyrians (2 Kings 17). The Southern Kingdom comprised the tribes of Judah and Benjamin (1 Kings 12:21), although Judah was the larger. At some point, people from Judah came to be called “Jews.” Not many texts clearly refer to them as Jews before the Babylonian captivity, with Jeremiah 34:9 being the primary pre-exile text that called the people in the Southern Kingdom “Jews.”
The Northern Kingdom (Israel) never shows up again in Scripture as a nation (though there are prophetic promises of their return, such as in Ezekiel 37:21–22), but Scripture does follow the Southern Kingdom (Judah) through its Babylonian captivity (see Daniel) and its return to their land (Ezra 1:1–3). Most Old Testament references to “Jew” appear in texts from and after the exile (e.g., Esther 2:5; Zechariah 8:23; Nehemiah 1:2).

from the new testament

Because only the Southern Kingdom returned to the land (see the Old Testament section), the primary term shifted from "Israelite" to "Jew," denoting the people of Judah. The New Testament primarily uses "Jew." However, because Judah was the remnant of Israel, "Jew" effectively referred to all of Israel. This allowed “people of Israel,” “Hebrews,” and “Jews” to be used more interchangeably. For example, referring to his lineage, Paul said, “I [am] … of the people of Israel, of the tribe of Benjamin, a Hebrew of Hebrews” (Philippians 3:5). Elsewhere, defending his apostleship and referring to false apostles, he said, “Are they Hebrews? So am I. Are they Israelites? So am I. Are they offspring of Abraham? So am I” (2 Corinthians 11:22).
In both of those previous examples, although Paul called himself a Jew (Acts 22:3), he did not make clear distinctions among the other terms. Thus, by the New Testament period, the terms largely overlapped in meaning.

implications for today

"That which we call a rose, by any other word would smell as sweet." Shakespeare's character Juliet used that line to imply that a name doesn't change the substance. The same might be said of “Hebrew,” “Israelite,” and “Jew"—though the first two have fallen out of favor today, replaced by “Jews” and “Israelis.” But the terms are less important than seeing how God has preserved the Jewish people for thousands of years, from a small people to now an established modern nation. He has a plan for the nation and will save many Jews just before Jesus returns (Zechariah 12:10; Romans 11:25–26).

His focus right now, though, is on spreading the gospel to all nations. He hasn't rejected the Jews, but the temporary Jewish rejection of her Messiah was the means God used to bring salvation to all nations (Romans 11:11).

Paul calls the true descendants of Abraham those who, like him, trust God in faith (Galatians 3:7). That's us. We're called to bring others into the salvation that God promised the Jews and extended to all people.

understand

The terms "Hebrew," "Israelite," and "Jew" developed at different stages in the history of God’s people and originally emphasized different aspects of their identity.
Over time, particularly after the exile, the terms increasingly overlapped, with "Jew" becoming the dominant label.
Although the terms are generally used interchangeably in the New Testament, each term has its own historical and theological background.
