Why does the poet say his tribe

In this poem, the speaker uses the metaphor of a "tribe" to refer to a group of people who share a common identity and purpose. He says that his tribe is "bound by blood and soil" to signify the strong connection they have to their ancestry and the land they inhabit. This connection is often based on shared history, culture, and values. The phrase "bound by blood" emphasizes the sense of kinship and belonging within the tribe, while "bound by soil" suggests a deep attachment to the physical environment and the place they call home.

By saying that his tribe is bound in this way, the poet is highlighting the importance of unity, solidarity, and shared identity within the group. It also underscores the idea of a collective experience and shared destiny that binds the members of the tribe together.
