I am currently studying the Sanctuary Message from the Bible and would like to start my study from the Camp instead of beginning at the Bronze Altar. Could you suggest the best sources for learning about this, particularly those that include quotations from Ellen G. White? Additionally, I am curious about the quality of Alex Ortega's lessons on this topic. Are they considered good and reliable for in-depth study?
Re the organization of the camp, here are a few quotes.

The Hebrew camp was arranged in exact order. It was separated into three great divisions, each having its appointed position in the encampment. In the center was the tabernacle, the abiding place of the invisible King. Around it were stationed the priests and Levites. Beyond these were encamped all the other tribes. {PP 374.3}

The government of Israel was characterized by the most thorough organization, wonderful alike for its completeness and its simplicity. The order so strikingly displayed in the perfection and arrangement of all God's created works was manifest in the Hebrew economy. God was the center of authority and government, the sovereign of Israel. Moses stood as their visible leader, by God's appointment, to administer the laws in His name. From the elders of the tribes a council of seventy was afterward chosen to assist Moses in the general affairs of the nation. Next came the priests, who consulted the Lord in the sanctuary. Chiefs, or princes, ruled over the tribes. Under these were "captains over thousands, and captains over hundreds, and captains over fifties, and captains over tens," and, lastly, officers who might be employed for special duties. Deuteronomy 1:15. {PP 374.2}

From the outset of the journey from Egypt, lessons had been given for their training and discipline. Even before they left Egypt a temporary organization had been effected, and the people were arranged in companies, under appointed leaders. At Sinai the arrangements for organization were completed. The order so strikingly displayed in all the works of God was manifest in the Hebrew economy. God was the center of authority and government. Moses, as His representative, was to administer the laws in His name. Then came the council of seventy, then the priests and the princes, under these "captains over thousands, and captains over hundreds, and captains over fifties, and captains over tens" (Numbers 11:16, 17; Deuteronomy 1:15), and, lastly, officers appointed for special duties. The camp was arranged in exact order, the tabernacle, the abiding place of God, in the midst, and around it the tents of the priests and the Levites. Outside of these each tribe encamped beside its own standard. {Ed 37.4}
