Luke 3:21-22

See the notes at Matthew 3:13-17. “Jesus being baptized;” or, Jesus “having been” baptized. This took place after the baptism, and not “during” its administration, Matthew 3:16.

Praying - This circumstance is omitted by the other evangelists; and it shows,

1. That Jesus was in the habit of prayer.
2. That it is proper to offer up special prayer at the administration of the ordinances of religion.
3. That it is possible to pray in the midst of a great multitude, yet in secret. The prayer consisted, doubtless, in lifting up the heart silently to God. So “we” may do it anywhere - about our daily toil - in the midst of multitudes, and thus may pray “always.”

Luke 3:22

In a bodily shape - This was a real visible appearance, and was doubtless seen by the people. The dove is an emblem of purity and harmlessness, and the form of the dove was assumed on this occasion to signify, probably, that the spirit with which Jesus would be endowed would be one of purity and innocence. The “Holy Spirit,” when he assumes a visible form, assumes that which will be emblematic of the thing to be represented. Thus he assumed the form of “tongues,” to signify the miraculous powers of language with which the apostles would be endowed; the appearance of fire, to denote their power, etc., Acts 2:3.
