IsaiahChapter 56

+ Secondary text Original text ← Previous Next →Contribute

This is what the LORD says: Keep justice and do what is right, for my salvation is close at hand and my righteousness is about to be revealed.

Blessed is the one who does this, the man who holds fast to it — who keeps the Sabbath without profaning it and keeps his hand from doing any evil.

Let no foreigner who has joined himself to the LORD say, "The LORD will surely exclude me from his people." And let no eunuch say, "I am nothing but a withered tree."

For this is what the LORD says: To the eunuchs who keep my Sabbaths, who choose what pleases me and hold fast to my covenant —

to them I will give, within my house and within my walls, a memorial and a name better than sons and daughters. I will give them an everlasting name that will never be cut off.

And the foreigners who join themselves to the LORD to serve him, to love the name of the LORD and to be his servants — all who keep the Sabbath without profaning it and hold fast to my covenant —

these I will bring to my holy mountain and give them joy in my house of prayer. Their burnt offerings and sacrifices will be accepted on my altar; for my house will be called a house of prayer for all peoples.

So declares the Lord GOD, who gathers the outcasts of Israel: I will gather still others to him, besides those already gathered to him.

All you beasts of the field, come and devour — all you beasts of the forest!

Israel's watchmen are blind, every one of them; they know nothing. They are all mute dogs that cannot bark, dreaming as they lie there, in love with sleep.

They are greedy dogs that never have enough. And they are shepherds who understand nothing; every one of them has turned to his own way, each seeking his own gain, to the last of them.

"Come," they say, "let me get some wine; let us drink our fill of strong drink! And tomorrow will be like today — even better, far grander!"

Summary2

Chapter 56

Main Theme: God opens salvation to all who keep his covenant, including foreigners and eunuchs, while criticizing Israel’s failing leaders.

Content: The chapter begins with an exhortation to uphold justice and righteousness because God’s salvation is near. Foreigners and eunuchs who join themselves to the Lord and keep the Sabbath are promised an eternal name and a place in God’s house. God promises that his house shall be called a house of prayer for all peoples. The chapter concludes with sharp criticism of Israel’s leaders (watchmen and shepherds) who are blind, mute, and self-centered.

Historical context

Historical and Cultural Context for Isaiah 56

People

Eunuchs (סָרִיס, saris): The chapter gives special attention to eunuchs, men who were castrated. In the ancient world, eunuchs often served at royal courts, including those of Babylon, Persia, and Egypt. Castration was practiced to ensure loyalty and to protect royal harems. For Israelites, this was particularly painful because Deuteronomy 23:2 excluded eunuchs from the assembly of the Lord. The eunuch’s complaint, "I am a dry tree" (v. 3), reflects the sorrow of being unable to continue one’s lineage—a fundamental value in Israelite culture.

Foreigners (בֶּן־הַנֵּכָר, ben-hannekar): The chapter also addresses non-Israelites who wished to join YHWH. During the exile and after the return, the question of foreigners’ status within the covenant community was highly relevant. Some texts, such as Ezra-Nehemiah, show a restrictive attitude, while Isaiah 56 presents an inclusive vision.

Places

My holy mountain and my house of prayer (v. 7): This refers to the temple in Jerusalem on Mount Zion. The phrase "a house of prayer for all peoples" points toward a universal vision where the temple is not only for Israel but for all nations. Jesus later quoted this text when he cleansed the temple (Mark 11:17).

Events and Customs

Sabbath observance: The Sabbath is repeatedly emphasized in the chapter (vv. 2, 4, 6) as the central identity marker for belonging to God’s covenant people. During the exile, when the temple lay in ruins, the Sabbath and circumcision became the most visible signs of Jewish identity. That Sabbath observance here becomes an entry requirement also for eunuchs and foreigners shows a radical rethinking of who belongs to God’s people.

Burnt offerings and sacrifices (v. 7): The text assumes a functioning temple system with sacrifices. This places the fulfillment of the vision either in the period after the temple was rebuilt (516 BCE) or as a future eschatological reality.

Key Terms

יָד וָשֵׁם (yad vashem) – "a memorial and a name" (v. 5): This expression literally means "hand and name" and refers to a lasting memory or monument. For eunuchs who could not have children, God promised something better than physical descendants—an eternal name that will not be cut off. This expression is today known as the name of Israel’s Holocaust memorial museum, Yad Vashem.

צֹפָיו עִוְרִים (tsofav ivrim) – "his watchmen are blind" (v. 10): Watchmen (prophets and leaders) who were supposed to guard the people are strongly criticized. They are compared to mute dogs that cannot bark—a highly derogatory image in a culture where dogs were seen as unclean scavengers. This marks a sharp shift from the oracle of inclusion to harsh criticism of Israel’s leaders.
