The phrase "brought one's knees" could be replaced with a number of different synonyms depending on the context. One possible option is "knelt down," which implies a deliberate lowering of oneself onto one's knees. "Kowed," on the other hand, suggests a more subservient or supplicatory posture. "Bowed," with its roots in traditional gestures of respect and submission, may also be appropriate. Other possibilities include "prayed," "genuflected," "prostrated," or simply "kneeling." Ultimately, the choice of which synonym to use will depend on the specific context and tone of the writing, as well as the writer's personal style and preferences.
