Paul speaks of his instructions as if they were objects that could be physically presented to the believers. Here, to place before means to instruct or to remind. Alternate translation: "If you help the believers remember these things" (See: [[rc://en/ta/man/translate/figs-metaphor]])
Paul speaks of God's word and its teaching as if it could physically feed Timothy and make him strong. This can be stated in active form. Alternate translation: "the words of faith and the good teaching that you have followed are causing you to trust more strongly in Christ" (See: [[rc://en/ta/man/translate/figs-metaphor]] and [[rc://en/ta/man/translate/figs-activepassive]])
