The photo in the Watchtower 14 11/15 shows a shelf of food in the corner.
They stated this in the article -
When Gog begins the assault, Jehovah will tell his servants: “Go, my people, enter your inner rooms, and shut your doors behind you. Hide yourself for a brief moment until the wrath has passed by.” (Isa. 26:20) At that crucial time, Jehovah will give us lifesaving instructions, and the “inner rooms” might well be connected with our local congregations.
18 If, therefore, we wish to benefit from Jehovah’s protection during the great tribulation, we must recognize that Jehovah has a people on earth, organized into congregations. We must continue to take our stand with them and remain closely associated with our local congregation. With all our hearts, may we join the psalmist in proclaiming: “Salvation belongs to Jehovah. Your blessing is upon your people.”—Ps. 3:8.
If they think the scripture in Isaiah applies then it specifically says to hide yourselves and yet they profess to be waiting on Jehovah to advise them where to hide. How is it, all of a sudden, that Jehovah will be communicating with them at this time but doesn't do so now?
They can't help but speculate and make things up, being far from discreet and going beyond what the Bible states.
