3377. Verses 4-5 And I will cause your seed to multiply as the stars of heaven, and I will give to your seed all these lands; and in your seed all the nations of the earth will be blessed, because Abraham hearkened to My voice and practiced My observances, My commandments, My statutes, and My laws.

'I will cause your seed to multiply as the stars of heaven' means truths and cognitions of faith 'And I will give to your seed all these lands' means derivative Churches. 'And in your seed all the nations of the earth will be blessed' means all with whom good is present, both inside and outside the Church. 'Because Abraham hearkened to My voice' means the union of the Lord's Divine Essence with the Human Essence by means of temptations. 'And practiced My observances, My commandments, My statutes, and My laws' means through revelations constantly coming from Himself.

In general, digging in the Bible means applying your own mind, your own faculties to find or create spiritual things. This is reflected in our everyday language; we often speak of investigators “digging for the truth.” In most cases, the idea of digging is connected with wells, and to dig a well means to investigate the Lord’s Word and draw ideas from it. In a more negative sense, a pit – which is like a well but with no water – represents falsity, so to dig a pit represents using your intellect to fabricate falsities. Finally, there is the idea of digging through walls in order to steal from others, which represents doing evil in a cunning and concealed way, invading someone’s life and attacking their desires for good and concepts of truth.

In Genesis 26:18, to dig signifies to open.
