"In reply the accused explained that their altar was not intended for sacrifice, but simply as a witness that, although separated by the river, they were of the same faith as their brethren in Canaan. They had feared that in future years their children might be excluded from the tabernacle, as having no part in Israel. Then this altar, erected after the pattern of the altar of the Lord at Shiloh, would be a witness that its builders were also worshipers of the living God. PP 519.1"
"And if we have not rather done it for fear of this thing, saying, In time to come your children might speak unto our children, saying, What have ye to do with the Lord God of Israel?"
The EGW passage directly echoes the concern expressed in Joshua 22:24 about future generations questioning the relationship of the tribes east of the Jordan with the Lord. The phrasing is very similar.
"endeavored to prevent future misapprehension and to remove what might be a cause of temptation. PP 519.3"
"Let us not therefore judge one another any more: but judge this rather, that no man put a stumblingblock or an occasion to fall in his brother’s way."
Both passages address the importance of avoiding actions that could lead others into temptation or misunderstanding. While not a direct quote, the underlying principle is shared.
"How often serious difficulties arise from a simple misunderstanding, even among those who are actuated by the worthiest motives; and without the exercise of courtesy and forbearance, what serious and even fatal results may follow. The ten tribes remembered how, in Achan's case, God had rebuked the lack of vigilance to discover the sins existing among them. Now they resolved to act promptly and earnestly; but in seeking to shun their first error, they had gone to the opposite extreme. Instead of making courteous inquiry to learn the facts in the case, they had met their brethren with censure and condemnation. Had the men of Gad and Reuben retorted in the same spirit, war would have been the result. While it is important on the one hand that laxness in dealing with sin be avoided, it is equally important on the other to shun harsh judgment and groundless suspicion. PP 519.4"
"He that answereth a matter before he heareth it, it is folly and shame unto him."
The EGW passage warns against answering a matter before hearing it, which is the core principle of Proverbs 18:13.
