Arcana Coelestia # 3622
3622. 'Like these of the daughters of the land' means because they are not from that ground, that is, from truths which the genuine Church knows. This is clear from the meaning of 'the daughters of the land' as Churches, for 'the daughters' means affections for good and truth, 2363, and 'the land' means the region where the Church is situated, and so means the Church itself, dealt with in 662, 1066, 1067, 1262, 1733, 1850, 2117, 2118 (end), 2928, 3355. 'The daughters of the land' accordingly means the goods and truths of the Church.
Keep
Keeping" in the Bible generally concerns the actions of life, though in some cases it can mean holding something away from the activities of life to safeguard it. By far the most common use of "keep" is connected with keeping the Lord's commandments or keeping feast days or rituals. These all mean putting true ideas from the Lord into action in life; simply knowing them or remembering them is not enough. In a deeper sense, it means worshiping the Lord, since living life according to His leading is the ultimate act of worship. When its not possible to act from the Lord's commandments, "keeping" represents remembering and safeguarding those true ideas so that they can be put into practice eventually.
