Moses continues to tell the people of Israel Yahweh's words. In verse 25 he speaks to the group as a group, so the forms of "you" are plural, but in verse 26 he speaks as if the Israelites are one person, so the forms are singular. (See: [[rc://en/ta/man/translate/figs-you]])
Even taking the gold or silver on the idols could cause the people to start worshiping them. By doing this they would become like an animal caught by a trap. This can be stated in active form. Alternate translation: "it will become a trap to you" (See: [[rc://en/ta/man/translate/figs-metaphor]] and [[rc://en/ta/man/translate/figs-activepassive]])
