ISB ~ Acts 20 v36

knelt down:A traditional prayer posture noted also in 21:5. Kneeling illustrates the proper relation between God and his servants, who express the submission of their hearts through the lowering of their bodies (Ps 95:6; Eph 3:14). Other prayer postures stemming from Jewish practice include raising the hands (Ps 141:2; 1 Tim 2:8) and standing (Mk 11:25; Lk 18:11; CCC 2702).
