Note 6 at Ac 9:40: Just like Jesus, Elijah, and Elisha, Peter sought seclusion when raising Dorcas from the dead (see note 2 at Lu 8:51).

Note 7 at Ac 9:40: Peter prayed before he spoke to Tabitha (Dorcas) and commanded her to arise. Peter's purpose in praying was to discern the Lord's will. It is always God's perfect will to heal (see note 1 at Mt 8:16 and note 2 at Mt 8:17). However, certain things can keep God's will from coming to pass (Mr 11:25-26, Jas 1:5-7, and 1Pe 3:7). Some degree of faith must be present among those receiving the miracle (see note 2 at Lu 7:13). There is a sin unto death that we are not supposed to pray for (1Jo 5:16), and there are many other possible hindrances that keep us from just commanding God's perfect will to come to pass.

When administering a healing or resurrection, as in this case, we must be led of God to deal with any situations that might hinder the manifestation of our answered prayer. Peter is not recorded as praying in Ac 3 when he healed the lame man, but he did listen to God and discern the situation (see note 2 at Ac 3:4).

Note 8 at Ac 9:40: This is the first account of Jesus' disciples raising someone from the dead. Paul raised a young man named Eutychus, in the town of Troas, from the dead (Ac 20:7-12). It is also possible that Paul himself was raised from the dead (Ac 14:19-20); at least those who were trying to kill him thought he was dead.
