Arcana Coelestia # 3065
3065. 'Behold, I am standing beside a spring of water' means a state when within the Human conjunction takes place involving Divine truth. This is clear from the meaning of 'a spring' as truth, dealt with in 2702, here Divine truth since the subject is the Lord. The state itself in which the conjunction takes place is meant by 'standing beside the spring'; and the fact that it was effected within the Human is evident from the train of thought.
Isaiah 33:15-16
15
He who walks righteously, and speaks blamelessly; He who despises the gain of oppressions, who gestures with his hands, refusing to take a bribe, who stops his ears from hearing of blood, and shuts his eyes from looking at evil--
16
he will dwell on high. His place of defense will be the fortress of rocks. His bread will be supplied. His waters will be sure.
