"The people of God will not be free from suffering; but while persecuted and distressed, while they endure privation and suffer for want of food they will not be left to perish. That God who cared for Elijah will not pass by one of His self-sacrificing children. He who numbers the hairs of their head will care for them, and in time of famine they shall be satisfied. While the wicked are dying from hunger and pestilence, angels will shield the righteous and supply their wants. To him that “walketh righteously” is the promise: “Bread shall be given him; his waters shall be sure.” “When the poor and needy seek water, and there is none, and their tongue faileth for thirst, I the Lord will hear them, I the God of Israel will not forsake them.” Isaiah 33:15, 16 ; 41:17 . GC 629.2"
"But the very hairs of your head are all numbered."
The EGW passage explicitly quotes Matthew 10:30 ('He who numbers the hairs of their head will care for them') and directly connects it to God's care for His people during times of suffering and famine. This is a clear and direct allusion.
"“Although the fig tree shall not blossom, neither shall fruit be in the vines; the labor of the olive shall fail, and the fields shall yield no meat; the flock shall be cut off from the fold, and there shall be no herd in the stalls;” yet shall they that fear Him “rejoice in the Lord” and joy in the God of their salvation. Habakkuk 3:17, 18 . GC 629.3"
"Although the fig tree shall not blossom, neither shall fruit be in the vines; the labour of the olive shall fail, and the fields shall yield no meat; the flock shall be cut off from the fold, and there shall be no herd in the stalls:"
EGW directly quotes Habakkuk 3:17.
"Yet I will rejoice in the Lord, I will joy in the God of my salvation."
EGW directly quotes Habakkuk 3:18.
"“The Lord is thy keeper: the Lord is thy shade upon thy right hand. The sun shall not smite thee by day, nor the moon by night. The Lord shall preserve thee from all evil: He shall preserve thy soul.” “He shall deliver thee from the snare of the fowler, and from the noisome pestilence. He shall cover thee with His feathers, and under His wings shalt thou trust: His truth shall be thy shield and buckler. Thou shalt not be afraid for the terror by night; nor for the arrow that flieth by day; nor for the pestilence that walketh in darkness; nor for the destruction that wasteth at noonday. A thousand shall fall at thy side, and ten thousand at thy right hand; but it shall not come nigh thee. Only with thine eyes shalt thou behold and see the reward of the wicked. Because thou hast made the Lord, which is my refuge, even the Most High, thy habitation; there shall no evil befall thee, neither shall any plague come nigh thy dwelling.” Psalm 121:5-7 ; 91:3-10 . GC 629.4"
"The Lord is thy keeper: the Lord is thy shade upon thy right hand. The sun shall not smite thee by day, nor the moon by night. The Lord shall preserve thee from all evil: he shall preserve thy soul."
Ellen White directly references Psalms 121:5-7 in this passage.
