1 Cor 10:1
Moreover, brethren, I would not that ye should be ignorant, how that all our fathers were under the cloud, and all passed through the sea;
10:2 And were all baptized unto Moses in the cloud and in the sea;
10:3 And did all eat the same spiritual meat;
10:4 And did all drink the same spiritual drink: for they drank of that spiritual Rock that followed them: and that Rock was Christ.
Ex 40:34 Then a cloud covered the tent of the congregation, and the glory of the LORD filled the tabernacle.
40:35 And Moses was not able to enter into the tent of the congregation, because the cloud abode thereon, and the glory of the LORD filled the tabernacle.
1 John 5:6
This is he that came by water and blood, even Jesus Christ; not by water only, but by water and blood. And it is the Spirit that beareth witness, because the Spirit is truth.
