10 I am a wall, and my breasts like towers: then was I in his eyes as one that found favour. 
10 I am a wall, and my breasts are like towers. Thus I have become in his eyes like one bringing contentment.
10 I was a wall, and my breasts were like towers; then I was in his eyes as one who finds
10 Dear brothers, I'm a walled-in virgin still, but my breasts are full - And when my lover sees me, he knows he'll soon be satisfied.
10 The Shulamite I am a wall, And my breasts like towers; Then I became in his eyes As one who found peace.
10 I was a virgin, like a wall; now my breasts are like towers. When my lover looks at me, he is delighted with what he sees.
Matthew Henry's Commentary on Song of Solomon 8:10
Commentary on Song of Solomon 8:8-12
(Read Song of Solomon 8:8-12)
The church pleads for the Gentiles, who then had not the word of God, nor the means of grace. Those who are brought to Christ themselves, should contrive what they may do to help others to him. Babes in Christ are always seen among Christians, and the welfare of their weak brethren is an object of continual prayer with the stronger believers. If the beginning of this work were likened to a wall built upon Him the precious Foundation and Corner-stone, then the Gentile church would become as a palace for the great King, built of solid silver. If the first preaching of the gospel were as the making a door through the wall of partition, that door should be lasting, as cased with boards of durable cedar. She shall be carefully and effectually protected, enclosed so as to receive no damage. The church is full of care for those yet uncalled. Christ says, I will do all that is necessary to be done for them. See with what satisfaction we should look back upon the times and seasons, when we were in his eyes as those that find favour. Our hearts are our vineyards, which we must keep with all diligence. To Christ, and to his praise, all our fruits must be dedicated. All that work for Christ, work for themselves, and shall be unspeakable gainers by it.
