To teach — The order of things in this verse is very observable; first he endeavours to understand God's law and word, and that not for curiosity or ostentation, but in order to practice: next he consciously practises what he did understand, which made his doctrine much more effectual: and then he earnestly desires and labours to instruct others, that they also might know and do it.
