I like both versions......
"God is within her, she will not fail; God will help her at break of day."
"God has taken his place in her; she will not be moved. He will come to her help at the dawn of morning."
-Bible in Basic English
"The poetic idea here seems to refer to the day as having turned away 'from' us at night, and then as turning about 'toward' us
in the morning, after having gone, as it were, to the greatest distance from us."
"God is in the midst of her....the church and people of God; not merely by his essence, power, and providence, as he is in the
midst of the world; but by his gracious presence, and which always continues, though not always perceived..."
-Gill's Exposition of the Entire Bible
