{c} Enlarge the place of thy tent, and let them extend the curtains of thy habitations: spare not, lengthen thy cords, and strengthen thy stakes;

(c) Signifying that for the great number of children that God would give her, she would seem to lack room to lodge them.

Wesley's Notes

54:2 Enlarge - That it may be capable of the Gentiles, who shall flock to thee in great numbers. Strengthen - That they may be able to support that great weight which the tents thus enlarged, shall be upon them.

Jamieson-Fausset-Brown Bible Commentary

2. (Isa 49:19, 20; Jer 31:31-36, 38, 39). Thy children shall be so many that thy borders must be extended to contain them.

curtains-the cloth forming the covering of the tent.

spare not-give abundantly the means for the enlargement of the Church (2Co 9:5-7).

cords . stakes-The more the tent is enlarged by lengthening the cords by which the cloth covering is fastened to the ground, the more the stakes supporting the tent need to be strengthened; the Church is not merely to seek new converts, but to strengthen those she has in the faith. The image is appropriate, as the tabernacle was the symbol of the old Israelitish Church (see on [855]Isa 33:20).

Matthew Henry's Concise Commentary

54:1-5 Observe the low state of religion in the world, for a long time before Christianity was brought in. But by preaching the gospel, multitudes were converted from idols to the living God. This is matter of great rejoicing to the church. The bounds of the church were extended. Though its state on earth is but mean and movable, like a tent or tabernacle, it is sometimes a growing state, and must be enlarged as the family increases. But the more numerous the church grows, the more she must fortify herself against errors and corruptions. Thy Maker is thy Husband. Christ is the Holy One of Israel, the Mediator of the covenant made with the Old Testament church. Long he had been called the God of Israel; but now he shall be called the God of the whole earth. And he will cleanse from sin, and cause every true believer to rejoice in this sacred union. We never can enough admire this mercy, or duly value this privilege.
