'For I know him' means that it is true. 'That he will command his sons, and his house after him, and they will keep the way of Jehovah to do righteousness and judgement' means that from Him comes the entire doctrine of charity and of faith, 'sons' meaning people governed by truths, 'house' those governed by goods, 'the way' doctrine, 'righteousness' in regard to good, 'judgement' to truth. 'In order that Jehovah may bring upon Abraham that which He has spoken concerning him' means that the Human Essence will for that reason be joined to the Divine Essence.
