Seek Yahweh, for the Great Deliverance is at Hand. Let the exiles seek Yahweh, for the time is at hand. His plans for His people reach beyond their own as far as the heavens are exalted above the earth. Even as the rain and snow descend and do not return, but make the earth fruitful, so Yahweh's promise, that has gone forth from His lips, shall be accomplished without fail. (An utterance was looked upon by the Hebrews almost as a personal power fulfilling itself.) He will lead forth the rejoicing exiles, mountains and trees shall rejoice aloud as the happy procession passes. The thorn-bush and the brier (?) or nettle (?) shall give place to the fir and the myrtle, an everlasting memorial of Yahweh's gracious deliverance.
Isaiah 55:6-13
6 Seek ye the LORD while he may be found, call ye upon him while he is near:
7 Let the wicked forsake his way, and the unrighteousb man his thoughts: and let him return unto the LORD, and he will have mercy upon him; and to our God, for he will abundantly pardon.
8 For my thoughts are not your thoughts, neither are your ways my ways, saith the LORD.
9 For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts.
10 For as the rain cometh down, and the snow from heaven, and returneth not thither, but watereth the earth, and maketh it bring forth and bud, that it may give seed to the sower, and bread to the eater:
11 So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it.
12 For ye shall go out with joy, and be led forth with peace: the mountains and the hills shall break forth before you into singing, and all the trees of the field shall clap their hands.
13 Instead of the thorn shall come up the fir tree, and instead of the brier shall come up the myrtle tree: and it shall be to the LORD for a name, for an everlasting sign that shall not be cut off.
