This is clear from the meaning of 'knowing' as discernment; and from the meaning of 'the midst of the land' as the place where those who belong to the Lord's Church are in possession of truth and goodness, the inmost part being where truth grounded in good is, 3436, 6068, 6084, 6103. Thus 'the midst (or middle) of the land' means the Church, in the same way as 'the land of Goshen' does, referred to immediately above in 7443. 'I am Jehovah' means that He is the only I AM, thus the only God - 'Jehovah' in the Word being the Lord, see 1343, 1736, 2921, 3023, 3035, 5663, 6303, 6905, 6945, 6956. From all this it is evident that 'to the end that you may know that I am Jehovah in the midst of the land' means the discernment that the Lord is the only God of the Church.
