A.T. Robertson Commentary Matthew 18:14

"Even so it is not the will of your Father who is in heaven, that one of these little ones should perish." — Matthew 18:14 (ASV)

The will of your Father (θελημα εμπροσθεν). Observe that Westcott and Hort read μου here rather than υμων after B Sahidic Coptic. Either makes good sense, though "your" carries on the picture of God's care for "each one of these little ones" (εν των μικρων τουτων) among God's children. The use of εμπροσθεν with θελημα is a Hebraism like εμπροσθεν σου in 11:25 with ευδοκια, "before the face" of God.
