Hosea uses this question to emphasize that the people will no longer be able to observe their festivals when their enemies defeat them and take them captive. AT: "You will not be able to celebrate the festivals that Yahweh appointed for you." (See: [[rc://en/ta/man/translate/figs-rquestion]])
Here "they" still refers to the people of Israel. You can continue stating this is second person. AT: "if you escape" (See: [[rc://en/ta/man/translate/figs-123person]])
# Egypt will gather them, and Memphis will bury them

# As for their treasures of silver—sharp briers will possess them
Briers growing in the places where Israelites stored their silver is spoken of as if the briers were human enemies that would take the Israelite's precious possessions for themselves. AT: "Sharp briers will grow where they store their treasures of silver" (See: [[rc://en/ta/man/translate/figs-metaphor]])
# sharp briers will possess them, and thorns will fill their tents
Here "sharp briers" and "thorns" mean the same thing. To have briers and thorns growing represents a land that has become desolate and like a wilderness. (See: [[rc://en/ta/man/translate/figs-doublet]] and [[rc://en/ta/man/translate/figs-metonymy]])
# their tents
Here "tents" represents the Israelites' homes. (See: [[rc://en/ta/man/translate/figs-metonymy]])
